Calculate the amount of charge on capacitor of $4\mu F .$ The internal resistance of battery is $1Ω:$

Calculate the amount of charge on capacitor of 4μ F . The internal resistance of battery is 1Ω:

Options

A $4\mu C$
B $8\mu C$
C $16\mu C$
Dzero

Correct answer

B. $8\mu C$

Step-by-step solution

Calculate the amount of charge on capacitor of 4μ F . The internal resistance of battery is 1Ω:

Using $i = \dfrac{5}{4 + 1} = 1A$

$∴ {V}_{AB} = i \times 4 = 4V ∴ {V}_{AC} = {V}_{CB} = 2$ Volt

$∴ q$ on $4\muF = C{V}_{AC} = 8\muC$
