The voltage and current at the terminals of the circuit element are zero for t < 0. For t >= 0 they are v = (10,000t+ 5)e^-400t V. and i = (40t + 0.05)e^-400t A.
a) at what instant of time is maximum power delivered to the element?
b)find the maximum power in watts
c)find the total energy delivered to the element in milli joules.
