Question

The correct answer is F just unsure of how to get there.

4 ptFrom a 7.00 V battery a capacitor is being charged up through a resistor with a resistance of 96.3 S2. The graph shows the voltage across the capacitor as a function of time. 10 8 7 2 4 2 0 1 2 3 4 5 6 789 10 t (s) What is the capacitance of the capacitor? Please, notice that e curve passes through at least one grid intersection point 23.

Explanation / Answer

Given  

R = 96.3 ohm

V = 7 V

Charging of capacitor, V = Vo [ 1 - e^(-t/RC)]

t = 5 seconds, V = 3 V

3 = 7 [ 1 - e^(-5/96.3 C) ]

On solving, by taking ln both side, we get

Capacitance, C = 9.278 x 101 Farad

So, correct answer is option (F)
