Question

mathematical expression for electric current​

Answer 1

Explanation:

Current is usually denoted by the symbol I. Ohm's law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm's law is I = V/R. ... Electric current generates an accompanying magnetic field, as in electromagnets.

Answer 2

Heya❤

The mathematical expression of electric current is given by OHM's Law;

$V=IR$

$I = \frac {V}{R}$

where,

I = Electric current

V= Potential Difference

R= Resistance
