b. Four circuits have the form shown in the diagram. The capacitor is initially uncharged and the switch S is open. The values of the emf, resistance R, and capacitance C for each for the circuits are circuit 1: emf = 18 V, R = 3 0, C = 1 pF circuit 2: emf = 18 V, R = 6 0, C = 9 JF circuit 3: emf = 12 V, R = 1 Q, C =7 pF circuit 4: emf = 10 V, R = 5 Q, C =7 pF Rank the circuits according to the current just after switch S is closed least to greatest.
