Answer to Question #296914 in Civil and Environmental Engineering for James

Question

A battery having a voltage source of cos t is connected to a series circuit on which the

inductance is 0.75 henry and the resistance is 15 ohms. Determine the current i at any time t if the

initial current is zero.

Answer 1

Inductance= 0.75

Resistance= 15ohms

series circuit

I=$\frac{V}{R^e}$​−tR/L

I= $\frac{cos t}{15}$ -15/0.75

I= (1/15)-(20)

I= 1.33A
