A voltage of Vo is applied from the battery to the RC circuit as shown in the figure. The potential difference across the capacitor is observed with the help of a voltmeter whose internal resistance is R = 10 R Vo M2. Calculate the time constant (t) of this RC circuit if the values of the resistor and capacitor are R=4 M2 and C=10µF, respectively. (Hint: Firstly, calculate equivalent resistance (R4) by considering that resistor, R, and internal resistor of voltmeter, R , are connected in parallel. Then calculate time constant as T=R„C .)
