Unformatted text preview: 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 60V 5A -VI=-300W 300W del. Dependent source 5V 1-50V 5A VI=-250W 250W del. Dependent source 2i 1 10V -10A -VI=100W 100W abs. 10V source 10V 5A -VI=-50W 50W del. 10A source -50V 10A -VI=500W 500W abs. c) For the circuit below, V A and V B are defined relative to the reference node as shown....
