Must show formula and units

R In the circuit shown, the switch S can be closed on either point A or C, but not at the same time. V 2 If V1 = V2 = 12 Volts RA R1 = R4 = 1.0 0 B R2 = R3 = 2.0 0 a. (2) What is the equivalent resistance between the points A and B? b. (3) Determine the current through R1 when the switch S is closed on A. c. (2) At what rate is energy dissipated by R1 when the switch S is closed on A? d. (3) Determine the current through R4 when the switch S is closed on C
