Equation to find current

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. WebSep 12, 2024 · To make Equation look like its dc counterpart, we use the rms values and of the current and the voltage. By definition, these are and where and With and , we obtain and We may then write for the average power dissipated by a resistor, This equation further emphasizes why the rms value is chosen in discussion rather than peak values.
