The voltage drop across an inductor in a circuit with a dc voltage source at time>> 5*time-constant is:_________

Sagot :

The voltage drop across an inductor in a circuit with a dc voltage source at time>> 5*time-constant is more than as compared to first case because the voltage across the inductor is proportional to the rate of change of current which is a maximum at the start when the current and the voltage across the resistor are zero.

As time progresses the current increases at a slower rate as does the voltage across the resistor but the voltage across the inductor decreases.

The voltage drop is proportional to the current, which is the rate-change of the charge. Inductors: V = L (DI/Dt). The voltage drop across the inductor is proportional to the rate-change of the current.

How do you calculate voltage drop in an inductor?

The formula which calculates the inductor voltage is

V= Ldi/dt,

where,

V is the voltage across the inductor,

L is the inductance of the inductor,

di/dt is the derivative of the current flowing across the inductor.

Thus from the above conclusion we can say that The voltage drop across an inductor in a circuit with a dc voltage source at time>> 5*time-constant is more than as compared to first case because the voltage across the inductor is proportional to the rate of change of current which is a maximum at the start when the current and the voltage across the resistor are zero.
