An initially uncharged 4.95 μF capacitor and a 7.17 kΩ resistor are connected in series at time t = 0 to a 1.50 V battery that has negligible internal resistance. What is the initial current I0 in the circuit in milliamperes? I0 = mA Calculate the circuit's time constant τ in milliseconds. τ = ms How much time t, in milliseconds, must elapse from the closing of the circuit for the current to decrease to 2.29% of its initial value? t = ms
