in the circuit shown in the figure, the S switch is closed at t=0 and the capasitors, which are completely empty, begin to fill. Here E=30V, C=3 uF and R=40 ohm.
A) what is the time constant of the circuit, T, in the units of microseconds?
B)when t=T, what is the total charge, in units of microcoulomb?
The remaining circuit quantities may change instantaneously as required by Kirchhoff's rules. Calculate I2 in amps immediately after the switch (t = 0+), in that order. (All currents in this and the following two should be positive.)
