12 VFigure 2:3.In figure 2. Assume the direction of the currents are correct but the polarity of the battery through which the current of 1A is flowing mayor may not be correct.(a) The current I-1+2 = 3A.(True, False)(b) For the loop on the left: -(3)(2) -e+ (1)(1) - 0 which leads to e- -5 indicating that the assigned polarity of the battery is incorrect.(True, False)(c) the resistance r can be found from: -(3)(2) + 12 - 3r =0 leading to r= 2.(True, False)(d) If (a) and (c) are true then the power dissipated by the resistor r and power supplied by the 12V battery are is 18 Watts and 36 Wattsrespectively.(True, False)(e) If (b) is true then the power dissipated by the 1n resistor, the 20 resistor and the power supplied to the 5V battery are 1 Watt, 12 Wattand 5 Watta respectively.(True, False)(F) If (d) and (e) are true the power delivered by the 12V battery is +36Watts. The power dissipated by the resistors are 41Watts andpower stored in the 5V battery is +5Watts. This indicates that energy is not conserved.(True, False)(g) The potential of the point b is lower than the potential of point a by 6V: V, - Va - 6.(True, False) 202(A)(B)Figure 1:1. Refer to figure 1.A. The capacitor is initially uncharged.

Refer to figure 1.B. The capacitor is initially uncharged. The switch S is closed at t= 0.Since the capacitor at t= 0+ behaves like a conducting wire[with zero resistance] and at t ao like an open circuit[ with infinite resistancel:(a) The effective resistance of the circuit at t= 0+ is: 4 +2+8- 5.60(True, False)(b) After a very long time (t - 0) the effective resistance of the circuit is: 4+ 2 - 60(True, False)(c) At t= o+ the voltages across the 82 resistor and 20 resistor are the same.(True, False)(d) At t= ot the voltage across 40, 8n and 20 resistors are 4.3V , 1.7V and 1.7V respectively.(True, False)(e) At t - o the voltages across the 8n resistor is zero because the capacitor is fully charged and lets no current pass through it[behaveslike an open circuit].(True, False)(f) At t- o the current is n- 1A.6V(True, False)(g) At t + oo the voltage across the 2n is 2V.(True, False)(h) At t- o the voltage across the 1F capacitor is 2V.(True, False)
