The ratio of heat produced in series and parallel combinations would be a b c d Answer:. Question 5: How is a voltmeter connected in the circuit to measure the potential difference between two points? Question 6: A copper wire has a diameter 0.

Question 7: The values of the current I flowing in a given resistor for the corresponding values of potential difference V across the resistor are given below: Plot a graph between V and I and calculate the resistance of that resistor. Question 8: When a 12 V battery is connected across an unknown resistor, there is a current of 2. Question 9: A battery of 9 V is connected in series with resistors of 0.

Answer: Since all the resistors are in series, the same current, 0. Question Several electric bulbs designed to be used on a V electric supply line, are rated 10 W.

Question A hot plate of an electric oven connected to V line has two resistance coils A and B, each of 24 Q resistance, which may be used separately, in series, or in parallel.

Question Two lamps, one rated W at V, and the other 60 W at V, are connected in parallel to electric mains supply. Question An electric heater of resistance 8 f2 draws 15 A from the service mains 2 hours.

Question Explain the following. Answer: a It has high melting point and emits light at a high temperature. Each of them dissipates energy and can withstand a maximum power of 18 W without Ncert Solutions Class 10th Maths Chapter 3 Sci melting.

Find the maximum current that can flow through the three resistors. Question 2: Should the resistance of an ammeter be low or high? Give reason. Answer: The resistance of an ammeter should be low so that it will not disturb the magnitude of current flowing through the circuit when connected in series in a circuit. Question 3: How does use of a fuse wire protect electrical appliances?

Answer: The fuse wire is always connected in series with the live wire or electrical devices. If the flow of current exceeds the specified preset value due to some reason, the heat produced Ncert Solutions For Class 10th Science Chapter 4 Water melts it and disconnects the circuit or the device from the mains.

In this way, fuse wire protects the electrical appliances. Question 4: What is electrical resistivity? In a series electrical circuit comprising a resistor made up of a metallic wire, the ammeter reads 5 A. The reading of the ammeter decreases to half when the length of the wire is doubled.

Answer: The resistance offered by a metallic wire of unit length and unit cross-sectional area is called electrical resistivity. Hence, when the length of wire is doubled, the resistance becomes double and current decreases to half. Calculate the resistance of the electric lamp. Question 6: Why is parallel arrangement used in domestic wiring?

Answer: Parallel arrangement is used in domestic wiring because i Each appliance gets the same voltage as that of the mains supply. Question 7: B 1, B 2 and B 3 are three identical bulbs connected as shown in figure.

When all the three bulbs glow, a current of 3A is recorded by the ammeter A. Answer: i Since B 1 ,B 2 and B 3 are in parallel, the potential difference across each of them will remain same.

So when the bulb B 1 gets fused, B 2 and B 3 have the same potential and continues with the same energy dissipated per second, i. Question 1: Three incandescent bulbs of W each are connected in series in an electric circuit. In another circuit, another set of three bulbs of the same wattage are connected in parallel to the same source. Justify your answer. Will the rest of the bulbs continue to glow in each circuit? Answer: a The bulbs in the two circuits will not glow equally bright as the current through them is not the same.

While the rest of bulbs in parallel circuit will continue to glow without getting disturbed because in parallel combination, current gets additional paths to flow. Question 2: Find out the following in the electric circuit given in figure: Answer: e No difference, since the ammeters are connected in series and same current will pass through them, so reading of both ammeters will be same.

Question 1. To determine the equivalent resistance of two resistors when connected in series, a student arranged the circuit components as shown in the diagram. But he did not succeed to achieve the objective. Question 2. For the given circuit, name the components which are connected in parallel. Because terminals of the resistance and voltmeter are connected together. Question 3.

A student arranges the following circuit to get equivalent resistance of a series combination of two resistors R 1 and R 2. Which one of the following statements will be true for this circuit [CCE ] a It gives incorrect reading for current I as well as potential difference V b It gives correct reading for current I but incorrect reading for potential difference V c It gives correct reading for potential difference V but incorrect reading for current I d It gives correct reading for both I and V Answer: b The voltmeter should be connected across the components of and R 2 to give correct reading for potential difference.

Question 4. An ammeter has 20 divisions between 0 mark and 2A mark on its scale. The least count of ammeter is a 0. Question 5. A student finds that there are 20 divisions between zero mark and 1V mark of a voltmeter. The least count of voltmeter is a 0. Question 6. The current flowing through a resistor connected in an electric circuit and the potential difference applied across its ends are shown in figure alongside. Question 7. Question 8. In an experiment on studying the dependence of the current I flowing through a given resistor on the potential difference V applied across it, a student has to change the value of the current.

For doing this, he should change the a number of cells used b resistor itself c ammeter used in the circuit d Voltmeter used in the circuit Answer: a If we change the number of cells in electric circuit, the potential difference will change and as a result current flowing in the circuit changes. Question 9. A milliammeter had graduations marked 0, , , , and The space between 0 mark Class 10th History Chapter 7 Ncert Solutions English and mark is divided into 20 divisions. Question To determine the eguivalent resistance of two resistors connected in series, a student prepared two electric circuits, correct reading of ammeter in the circuits is [CCE ] a In circuit I, 1.

When parallel resistors are of three different values, the potential difference across its terminals is [CCE ] a greatest across smallest resistance b greatest across largest resistance c equal across each resistance d least across the smallest resistance Answer: c Potential difference across each resistor is same in parallel combination of resistors.

Charge Something associated with the matter due to which it produces and experiences electric and magnetic effects. Resides on the outer surface of the conductor. Types of Current Direct Current Current whose magnitude and direction does not vary with time. Alternating Current Current whose magnitude and direction periodically changes with time. Resistance R : Obstruction offered to flow of electrons. After stretching, if length increases by n times then resistance will increase by n 2 times i.

Electric Circuit The arrangement of various electrical components along which electric current flow. Heating Effect of Electric Current As current flows through a conductor, the free electrons lose energy which is converted into heat. Elements of Circuit Cell Direct current source of electromotive force.

Combination of two or more cells is called battery.
