Answer 1

Answer:

The potential difference at a point is given by the expression: V= W/q. Where, V- potential difference, W- work done and q- coulomb.

The electric current's mathematical expression is :-

I= q/t. where, I is the electric current, q is charge and t is the time.

Ohm's law = Physical conditions remaining the same the electric current flowing thorough a conductor is directly proportional to the potential difference across the two ends of the conductors.

Mathematically, V= IR. Where V is the potential difference, I is the current and R is the resistance.

Also, Resistance =

R= V/I.

The resistance of a conductor is given by the expression R= rho into L / area of cross section of the conductor.
