2.7 b) Three capacitors of capacitances 2 pF, 3 pF and 4 pF are connected in parallel. (b) Determine the charge on each capacitor if the combination is connected to a 100 V supply.
Given, 3 capacitors connected in parallel with
Supply voltage
Since they are connected in parallel, the voltage across each capacitor is 100V.
So, Charge on 2pf Capacitor :
Charge on 3pF Capacitor:
Charge on 4pF Capacitor:
Hence charges on Capacitors are 2pC,3pC and 4pC respectively.
