Rl Series Circuit Diagram. Steps to draw the phasor diagram of rl series circuit. The voltage drop across the resistance v r i r is drawn in phase with the current i.
For example current is still the same everywhere in this series circuit. As the current lags voltage by an angle of 90 degrees in the pure inductive circuit. A first order rl circuit is one of the simplest analogue infinite impulse response electronic filters.
It consists of a resistor and an inductor either in series driven by a voltage source or in parallel driven by a current source.
In case of resistor both voltage and current are in same phase. R is in ohms. We know that. The time constant τ of the lr series circuit is given as l r and in which v r represents the final steady state current value after five time constant values.
