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. WebAny imbalance current comes from leakage from the conductors to ground or elsewhere. To measure this current, a leakage clamp meter should be able to read less than 0.1 mA. For example, taking a measurement on a 240 V ac circuit with all loads disconnected might result in a value of 0.02 A (20 mA) leakage. This value represents an insulation ...
