Question

write the formula and SI unit for electric current and potential difference​

Answer 1

Answer:

SI unit of electric current (I) is Ampere(A)

Formula: I = V/R

SI unit of potential difference (V) is Volt(V)

Formula: V = IR

Answer 2

Answer:

ampere SI unit of electric current and potential difference of one Volt is equal to one Joule of energy being used by one Coulomb of charge when it flows between two points in a circuit.

Explanation:

if a charge Q flows through the cross-section of a conductor in time t, the current I then I=Q/t. The S.I unit of charge is coulomb and measurement of electric current happens in units of coulomb per second which is 'ampere'.
