Question

If voltage applied on a capacitor is increased from V to 2V, choose the correct conclusion.

a) Q remains the same, C is doubled b) Q is doubled, C doubled.

c) C remains the same, Q is doubled d) Both Q and C remain same​

Answer 1

Answer:

c) C remains the same, Q is doubled

Explanation:

Q=CV

here, capacitance is constant

so, Q will be doubled

Answer 2

If voltage applied on a capacitor is increased from V to 2V, Q is doubled and C remains same(b)

• The expression Q=C V is the formula relating charge Q and Voltage V.
• Capacitor is a constant of proportionality.
• Capacitance of a capacitor depends on the shape,size and the dielectric medium present between the plates.
