The capacitance of a parallel plate capacitor is 2mF and the charge on its positive plate is 2mC. If the charge on its plates are doubled, the capacitance of the capacitor (Battery connected) –
A
Becomes 4mF
B
Becomes 1mF
C
Remains 2mF
D
Data insufficient
Answer
Becomes 4mF
Explanation
Solution
Q = CV As Battery connected V is unchanged.
