A capacitor is charged to a potential of 12.0 V and is then connected to a voltmeter having an internal resistance of 3.90 MΩ. A
iren2701 [21]

Explanation:

(a)  Formula to calculate the capacitance is as follows.

           V_{c} = V_{o} (e^(\frac{-t}{RC}))

Now, putting the given values into the above formula as follows.

          V_{c} = V_{o} (e^(\frac{-t}{RC}))

          3.5 V = 12 V (e^(\frac{-3.50 sec}{3.90 \times C}))

    e^(\frac{-3.50 sec}{3.90 \times C}) = 0.291

or,       \frac{-3.50 sec}{3.90 \times C} = ln (0.291)

      \frac{-3.50 sec}{3.90 \times C} = -1.23

              C = 0.729 F

Hence, the value of capacitance is 0.729 F.

(b)   Formula to calculate the constant of circuit is as follows.

               T = R \times C

                  = 3.1 \times 0.729

                  = 2.259 sec

Therefore, the time constant of the circuit is 2.259 sec.
