Question

I need help with DE's involving electrical circuits...anyone willing to help

Answer 1

I'll try to help you, post your question:)

Answer 2

Vs=cos(wt), R(resistor) and L(inductor) are connected in series. supply a characteristic equation of the circuit. I only know it must be a DE

Answer 3

We have

Let the voltage across Resistor be VR
and voltage across inductor be VL
source is Vs= cos wt
let the current through the circuit be \(I\)
