How do you calculate RL in a circuit

  RL CIRCUIT

•    RL means Resistor and Inductor .

RL circuit mainly two type

        1)RL series circuit.

        2)RL parallel circuit.

1)    RL SERIES CIRCUIT

RL series circuit

•  Power factor is lagging .
• Series circuit have current constant.
• Series circuit have always voltage calculated.

IMPEDANCE OF RL SERIES CIRCUIT

           Z=√R²+X_L²

VOLTAGE OF RL SERIES CIRCUIT 

          V= √V_R²+V_L²

CURRENT OF RL SERIES CIRCUIT

         I=V/Z

POWER FACTOR OF RL SERIES CIRCUIT 

        P.F=V_R/V

2)    RL PARALLEL CIRCUIT  

RL parallel circuit

• Parallel circuit have always voltage constant
•  Parallel circuit have always current calculated

 CURRENT CALCULATED BY RL PARALLEL CIRCUIT

            I=√I_R²+I_L²

 POWER FACTOR OF RL PARALLEL CIRCUIT 

             P.F=I_R/I
