Step 1
Impedance (Z) is defined as the ratio of the voltage across the circuit to the current flowing through it. It is given by the formula: \[ Z = \frac{V}{I} \] where \( V \) is the voltage and \( I \) is the current. Show more…

If a circuit has a voltage of 120 volts and a current of 8 + 6j amps, find the impedance of the circuit in rectangular form. Explain why do we use complex numbers in circuits?

Two impedances Z1 = (10+j5) and Z2 = (8+j6) are connected in parallel across a voltage of V = 200+j0. Calculate the circuit current, power factor, and reactive power.
In an electric circuit the applied alternating emf is given by E = 100sin314t volts and current flowing I = sin(314t + ?/3), Then, the impedance of the circuit will be ? in ohm.
