Consider the circuit shown in Figure 1. V1 is a 7.2 kHz sine wave with an amplitude of 4 V.Figure 1: RC Circuit Schematic1. Determine the total impedance (Z) of the circuit.2. Using V1 as a zero-phase reference, calculate the values of the following:a) Amplitude and phase of current (I)b) Amplitude and phase of voltage across R1 (VR1)c) Amplitude and phase of voltage across C1 (VC1

An impedance z₁ = 8j5ohms is in parallel with an impedance z₂ = 3 + j7ohms. If 100V are imposed on the parallel combination. Find the branch current 11, 12 and the resultant current. Draw the corresponding phasor diagram showing each current and voltage drop across each parameter. Calculate also the equivalent resistance, reactance and impedance of the whole circuit.
