Question 2 An electric circuit contains an electromotive force, E (supplied by a battery), a resistor R, an inductor L, and a capacitor C, in series as follows: Figure 1: Electric circuit with resistor, inductor, capacitor and battery If the charge on the capacitor, Q(t) is measured at different time t as in Table 1. Table 1: Charge at different time Time, t0 0.2 0.4 0.6 0.8 Charge, 0 6.2914 8.8086 9.4881 9.5356 Q(t) Kirchhoff's voltage law says that the sum of the voltage drops is equal to the supplied voltage which represented by the following equation: dQ dQ 1 L de dt +Q=E(t) Given that R = 20 0, L = 1H, C = 16 x 10- F. +R Estimate the electromotive force, E(t) at its highest accuracy for each of time recorded as in Table 1.
