Current Calculator

Calculate electric current using different formulas

Method 1: Ohm's Law (I = V/R)

Voltage (V):

Resistance (ohms):

Method 2: Charge Flow (I = Q/t)

Charge (Coulombs):

Time (seconds):

Method 3: From Power

Power (Watts):

Current Formulas

Ohm's Law: I = V / R

Definition: I = Q / t

Power: I = P / V or I = sqrt(P / R)

1 Ampere = 1 Coulomb per second
