The current through inductance l is given by i=i0e−t/τ a.) find an expression for the potential difference δvl across the inductor. b.) evaluate δvl at t=0s , if l=15mh , i0=36ma , and τ=1.1ms c.) evaluate δvl at t=1ms , if l=15mh , i0=36ma , and τ=1.1ms d.) evaluate δvl at t=2ms , if l=15mh , i0=36ma , and τ=1.1ms e.) evaluate δvl at t=3ms , if l=15mh , i0=36ma , and τ=1.1ms
