Question
The current through a 0.5 H coil is provided. Use the sine function to write a sinusoidal expression for the voltage across the coil. \[ i(t) = 7 \sin(377t - 70^\circ) \] This equation describes the current \( i(t) \) as a sinusoidal function, where the amplitude is 7, the angular frequency \( \omega \) is 377 rad/s, and the phase shift is \(-70^\circ\). The task is to use this information to determine the voltage across the coil by applying the appropriate sinusoidal expression.
