Question

7. If a 2 microfarad capacitor and 4microfarad capacitor are connected in parallel. What is the equivalent capacitance?​

Answer 1

Answer:

C

P

=2+4=6μF

orC=3μF

Total charge

Q=CV=3×12=36μC

voltage across 6μF capacitor =

6μF

36μC

=6V

∴ Voltage across each of 2μF and 4μF capacitors

=12V−6V

V=6V
