Question 546: Electrostats & Capacitance

Question

The potential on the plates of capacitor are $$+20 \mathrm{~V}$$ and $$-20 \mathrm{~V}$$. The charge on the plate is $$40 \mathrm{C}$$. The capacitance of the capacitor is

Accepted Answer

$$\begin{aligned}
V & =20-(-20)=40 	ext { volt } \
Q & =40 C \
C & =\frac{Q}{V} \
	herefore \quad C & =\frac{40}{40} \
	herefore \quad C & =1 F
\end{aligned}$$

Answer

2 F

Answer

1 F

Answer

4 F

Answer
