1. (a) What do you understand by the term electric potential?
(b) Define electric potential in terms of the energy spent
(c) State the unit of electric potential and define it.
Answers
Answer:
a. Electric potential, the amount of work needed to move a unit charge from a reference point to a specific point against an electric field.
b. Electric potential: The amount of energy spent in moving a unit positive charge from infinity to a given point in an electric field is called electric potential.
c. Volt is the SI unit of electric potential. One volt: When one coulomb of charge is brought from infinity to a given point in an electric field, such that work done is one joule, then the electric potential is said to be one volt.
Answer:
1. Electric potential, the amount of work needed to move a unit charge from a reference point to a specific point against an electric field.
2. The amount of energy spent in moving a unit positive charge from infinity to a given point in an electric field is called electric potential.
3. In the International System of Units (SI), electric potential is expressed in units of joules per coulomb (i.e., volts), and differences in potential energy are measured with a voltmeter.
