A resistor and inductor are connected in parallel. The resistor has a resistance of 24 ohms and the inductor has an inductive reactance of 20 ohms. What is the impedance of the circuit?
Solution
Z1 = 2pi f L
f = 50 hz
2pi (50) 20
Z2 = 24 ohms
z net = 2pi (50) 20 * 24 / 2pi (50) 20 + 24
z net = 6280 * 24 / 6280 + 24
Z net = 23.91 ohms
