In the Circuit Shown in Figure, a Generator Supplies a Voltage

question 65

Short Answer

In the circuit shown in Figure, a generator supplies a voltage of $E ( t ) = 20 \sin 60 t$ volts, the inductance is $2 H$ , the resistance is $40 \Omega$ , and $I ( 0 ) = 2 A$ . Find the current $0.2 \mathrm {~s}$ after the switch is closed. Round your answer to two decimal places.
