If 300 joules of work is required to transfer 30 coulombs of charge, then the potential difference between two ends of battery is
900 V
10 V
0 V
100 V
(a) What do you understand by the term "potential difference"? (b) What is meant by saying that the potential difference between two points is 1 volt? (c) What is the potential difference between the terminals of a battery if 250 joules of work is required to transfer 20 coulombs of charge from one terminal of battery to the other? (d) What is a voltmeter ? How is a voltmeter connected in the circuit to measure the potential difference between two points. Explain with the help of a diagram. (e) State- whether a voltmeter has a high resistance or a low resistance. Give reason for your answer.
If the work done to transfer 10 C of charge between two bodies A and B is 10 joules then find the potential difference between them.
The work done (in Joule) in carrying a charge of 100 coulomb between two points having a potential difference of 10 volt is:
In 10 seconds a charge of 25 coulomb leaves a battery and 200 joules of energy are delivered to an outside circuit as a result.what is the potential difference across the battery?
