Question

A 6.0 μF capacitor is fully charged and connected through a 100 Ω resistor. The time it takes for the capacitor to discharge at 37% of its initial charge is:
a.3.2 x 10-5 s
b.4.8 x 10-5 s
c.6.6 x 10-5 s
d.6.0 x 10-4 s

Answer 1

Given data:

Capacitance =

Resistance =

We know that time taken for the capacitor to discharge to 37% of its initial value is given by:

Where R  is the resistance

C is the capacitance of the capacitor

Substituting the values in the above formula we get:

Therefore option d) is the correct answer
