Rl Series Circuit Formula. When a series connection of a resistor and an inductor an rl circuit is connected to a voltage source the time variation of the current is. That is τ is the time it takes v l to reach v 1 e and v r to reach v 1 1 e.
This time constant τ is measured by τ l r in seconds where r is the value of the resistor in ohms and l is the value of the inductor in henries. Power in an rl circuit. These equations show that a series rl circuit has a time constant usually denoted τ l r being the time it takes the voltage across the component to either fall across the inductor or rise across the resistor to within 1 e of its final value.

These equations show that a series rl circuit has a time constant usually denoted τ l r being the time it takes the voltage across the component to either fall across the inductor or rise across the resistor to within 1 e of its final value. As we might have expected this exceeds the source voltage by a substantial amount and the phase shift is the reason for it. I i0 1 e t τ turning on where i0 v r is the final current. Power dissipated by the resistor in the form of heat p i 2 r watts.
