FIGURE 2 shows a circuit which is used to charge a capacitor of 50 F which is initially without charge. The circuit consists of a voltage source of 12 V, resistor of 800 k2, switch S and galvanometer G. (a) What is the time constant of the charging circuit? (b) At t=0 s, switch S is closed, and the capacitor is let to charge until saturated. What changes will you observe on the deflection of galvanometer pointer during the charging process? i. Sketch a graph of current, I against time, t. ii. 12 V S 800 ww A G FIGURE 2 50 F FIGURE 2 shows a circuit which is used to charge a capacitor of 50 F which is initially without charge.
