Question

Calculate the capacitance of a system that stores 1.0 10-10 C of charge at 100.0 V

A) 1.0 x 10^12
B) 1.0 x 10^8
C) 1.0 x 10^-12
D) 1.0 x 10^-8

Answer 1

Capacitance is charge/volts ratio.  So C=(1.0e-10C)/100V = 1e-12F.  Or 1pF  where pF is picoFarad

Answer 2

Answer : The charge stored in the system is
`1* 10^(-12)\ C`

Explanation :

It is given that,

Stored charge,
`Q=1* 10^(-10)\ C`

Voltage,
`V=100\ V`

We know that the capacitance of a system is given by :

`C=(Q)/(V)`

`C=(1* 10^(-10)\ C)/(100\ V)`

`C=1* 10^(-12)\ C`

So, the correct option is (C).

Hence, it is the required solution.
