1. Suppose the current in a conductor decreases exponentially with time according to the equation I(t) = I0sin(π/10t) where I0 =10 A is the initial current (at t = 0) and t is a constant having dimensions of time. Consider a fixed observation point within the conductor. How much charge passes this point between t = 0 and t=5 s?
1) so that the current varies by less than 10% as the load resistance (R) changes from 200 to 500N. The current must be at least 1.5 mA. For V = 10 Volts, find a resistance R which will meet these criteria. You want to make a current source from a battery (V) and resistor (R) R I V- RL
