Answers
Given : a resistance is added in series to capacitor
To Find : what changes will occur in the current flowing in the circuit and phase angle between voltage and current
Solution:
current leads the voltage in pure Capacitive circuit by π/2
Voltage ( EMF) & current are in same phase for pure resistive circuit
Hence when a resistance is added in series to capacitor
Impedance will increase Hence Current will be reduced
phase angle between voltage and current will be between 0 and π/2
Hence Phase angle and current both will decrease .
inductive circuits
Positive phase for inductive circuits
current lags the voltage in pure inductive circuit by π/2
Hence Voltage lead the current by π/2
EMF lead the current by π/2 in pure inductive circuit
Capacitive circuits
Negative phase for Capacitive circuits
current leads the voltage in pure Capacitive circuit by π/2
Hence Voltage lags the current by π/2
EMF lags the current by π/2 in pure Capacitive circuit
Resistive circuits
Voltage ( EMF) & current are in same phase for pure resistive circuit
current flowing in the circuit with capacitor
