Ldt/dI+RI=E I(0)=0
Here I is current, E is voltage, L is inductance, and R is resistance in a simple circuit. L and R are constant, and in class we assumed that E is constant as well. However, the voltage used in the electrical grid of the US is alternating. In this problem we assume that
E=E(t)=sint
Solve the differential equation, with the given initial condition, to get I=?
