Current and charge formula
WebIf the electric power and the total resistance are known, then the current can be determined by using the following formula: I = √ (P / R) Corresponding units: Ampere (A) = √ (Watt … WebI = Δ Q / Δ t. I is the current in amps (A). ΔQ is the electric charge in coulombs (C), that flows at time duration of Δt. Δt is the time duration in seconds (s). Example. When 5 coulombs flow through a resistor for duration of 10 seconds, the current will be calculated by: I = Δ Q / Δ t = 5C / 10s = 0.5A.
