Total series resistance Formula Rt = R1 + R2 + R Total Resistance in Parallel Rt = 1/ (1/R1 + 1/R2 + 1/R3) Voltage Calculation E = I x R Power calculation P = I x E Total power in a parallel circuit P = I x E Main line current calculation I = I1 + I2 + I Total inductance L = 1/ (1/L1 + 1/L2 + 1/L3) Total inductive reactance X = 2πfL Total Capacitance C = 1/ (1/C1 + 1/C2 + 1/C3)
Total Capacitive Reactance C = 1/ 2πfX Calculating RC time constant T = R x C Voltage Divider Circuit R = RL/ Transformer Ratio/Turns Ratio TR = Np/Ns Transformer Efficiency Transformer Efficiency % = (Power in/Power out) x 100 E represents what? Volts/Watts I/A represents what? Current R represents what? Ω/Ohms/Resistance P represents what? Power f represents what?
