1.	The instantaneous current and voltage of an a.c. circuit are given by i=0 sin 3000 t A and v=200 sin 300 t V. What is the power dissipation in the circuit?
Answer» We have given, `i=10sin 100t A and V = 200 sin 300 t V` `:. i_(0) = 10A and V_(0)=100V` `:.` Average power dissipation `=V_(0)i_(0)` `=100xx10=1000W`.
