Final Review Problem 1. Conceptual Problems a) In the circuit below, resistor R is increased. What happens to the following quantities? (Circle the appropriate answer.) V R1 R R2 R3 Power dissipated in R1 increases decreases stays the same Power dissipated in R2 increases decreases stays the same Power supplied by voltage source increases decreases stays the same Voltage across R3 increases decreases stays the same b) Find the power associated with each element in the circuit below. State whether each source is supplying or absorbing power. 10V 5A 2I 1 5V 1 10A I 1 - V 1 + Element Voltage Current Power Absorbed or delivered 5A source -60.0V 5.00A -0.300kW delivered Dependent source 5V 1 -50.0V 5.00A -0.250kW delivered Dependent source 2i 1 10.0V -10.0A 0.100kW absorbed 10V source 10.0V -5.00A -50.0W delivered 10A source -50.0V 10.0A 0.500kW absorbed
