For the circuit shown below determine whether the load Z0 is

For the circuit shown below, determine whether the load Z_0 is capacitive or inductive under the following conditions: the, power factor is 0.76 leading the. power factor is 0.5 lagging i_0{t) = cos omegat A v_0 (t) 5 cos omega t V i_0 (t) = 10 cos (omega t - pi/4)A v_0 (t) = 50 cos omega t

Solution

A) AS POWER FACTOR IS LEADING, THE IMPEDANCE IS CAPACITIVE LOAD

B) AS POWER FACTOR IS LAGGING, THE IMPEDANCE IS INDUCTIVE LOAD

C) AS BOT VOLTAGE & CURRENT PHASORS ARE IN PHASE WITH EACH OTHER, THE IMPEDANCE IS RESISTIVE

D) AS CURRENT LAGS THE VOLTAGE BY PI/4 THE IMPEDANCE IS INDUCTIVE IN NATURE.
