Define
A. Current
B. Potential Difference
C. Resistance
And give relation between them.
Answers
A. Current is defined as the Rate of flow of charges. It's SI unit is Ampere. Ampere is represented by 'A'.
B. Potential difference is defined as the work done in moving a unit positive charge from one point to another. It's SI unit is Volt. Volt is represented by 'V'.
C. Resistance is defined as the property of a conductor due to which it resists the flow of current through it. SI unit of resistance is ohm.
The relation between Current, potential difference and Resistance is
V = IR
This is ohm's law.
Hope this helps you:)
pls mark as brainliest
Answer:
Explanation:
A stream of electrons moving through a conductor constitutes an electric current it is given by I=q/t
potential difference between shall difference between two points in an electric circuit carryingsome current as the work done to move a unit charge from one point to another V=W/Q
Resistance properly of substance due to which it opposes the flow of electrons
V=IR
