In the circuit given below, the charge in C , on the capacitor having 5 F is
Options
- A4.5
- B9
- C7
- D15
Correct answer
B. 9
Step-by-step solution
Potential difference across the branch de is 6 ~V . Net capacitance of de branch is 2.1 F So, q=C V q =2.1 6 C q =12.6 C Potential across 3 F capacitance is V = 12.6 3 =4.2 volt Potential across 2 and 5 combination in parallel is 6-4.2=1.8 ~V So, q^ =(1.8)(5)=9 C
