Difference between Voltage and Current

Q1

Define voltage.

Voltage, also called electromotive force, is simply the energy per unit charge. In other words, voltage is the difference in electric potential between two points.

Q2

Define current.

Current is just the rate of flow of electric charge. In simple words, the current is the rate at which electric charge flows in a circuit at a particular point.

Q3

What is electric potential energy?

The electric potential energy of any given charge or system of changes is termed as the total work done by an external agent in bringing the charge or the system of charges from infinity to the present configuration without undergoing any acceleration.

Q4

Define 1 Ampere.

The SI unit of electric current is Ampere (A), 1 ampere is the amount of current when there is a flow of 1 coulomb of charge passing through a cross-section in 1 second.

Q5

What happens to the current when voltage is increased?

According to Ohm’s law, the law states that the electrical current, I, is proportional to the voltage, V and is inversely proportional to the resistance, R. Therefore, when voltage is increased, current also increases provided that the resistance in the circuit is maintained.
