Assuming the numerical values presented BELOW for a particular RC Circuit (two resistors in parallel, one in series both with the pair and with the capacitor), find the amount of time for the current to decay to half its original value.
Emf = 9 Volts.
C = 100 micro-Farads.
R1 (in main loop of circuit, series with battery and capacitor) = 400 Ohms.
R2 = 200 Ohms,
R3 = 300 Ohms.
R2 and R3 are both in parallel with each other.
But that parallel configuration itself is in series with everything else.
