Problem
The current in a fixed 10Ω resistor varies with time as I(t)=2.0+0.5t, where I is in ampere and t in second.
(a) Write the expression for the instantaneous potential difference across the resistor as a function of time.
(b) Find the potential difference at t=4s.
(c) Calculate the total charge that passes through the resistor from t=0 to t=4s.
