JEE PYQ: Capacitance Question 26
Question 26 - 2019 (08 Apr Shift 2)
A parallel plate capacitor has $1\mu$F capacitance. One of its two plates is given $+2\mu$C charge and the other plate, $+4\mu$C charge. The potential difference developed across the capacitor is:
(1) 3 V
(2) 1 V
(3) 5 V
(4) 2 V
Show Answer
Answer: (2)
Solution
$V = \frac{Q}{C} = \frac{Q_1 - Q_2}{2C} = \frac{4 - 2}{2 \times 1} = 1$ V.
