Question
(i) What happens to the magnitude of the charge on each plate of a capacitor if the potential difference between the conductors is doubled?It becomes four times larger.
It becomes two times larger.
It is unchanged.
It becomes one-half as large.
It becomes one-fourth as large.
(ii) If the potential difference across a capacitor is doubled, what happens to the energy stored?
It becomes four times larger.
It becomes two times larger.
It is unchanged.
It becomes one-half as large.
It becomes one-fourth as large.
Explanation / Answer
a) C =Q/V, Q = CV
IF V IS DOUBLED, CHERGE ALSO DOUBLES. I.E It becomes two times larger.
b) u = v^2/2C, if V is doubled, It becomes four times larger.
