Answer»

A RL Series Circuit consists basically of an inductor of inductance, L connected in series with a resistor of resistance, R. A first-order RL circuit is composed of one resistor and one inductor and is the SIMPLEST type of RL circuit.Current in a RL series circuit is given by:VR(1−e−RtL)VR(1−e−RtL)t is the time.The time required for the current flowing in the LR series circuit to reach its MAXIMUM STEADY state value is equivalent to about 5 time constants. This time constant ττ, is MEASURED by τ=L/Rτ=L/R, in seconds,ANSWER and Explanation:Current in a RL series circuit is :VR(1−e−RtL)R=10V=6L=10mHVR(1−e−RtL)R=10V=6L=10mHThis time constant..
