When the switch S is moved from open (shown) to closed, a) the current through R1 decreases. b) the current through R; increases. the total dissipated power increases. d) the total dissipated power decreases. 2) Three 100 Q resistors are connected in parallel (left). Another three 100 Q resistors are connected in series (right). If the same voltage is applied to each combination, which dissipates the larger power? a) L“ The parallel combination. b) The series combination. 0) Both produce the same power. d) Which power is larger depends on the applied voltage. 3) Three identical R = 10 £2 resistors are connected to an unknown resistor R1? as shown. A +20 volt battery is connected to terminal (a) and terminal (b). a) If the current through R; is I: l A, as shown, find R1. b) Find the voltage across R1. c) Find the total power dissipated in the circuit.
