a) In the circuit below, resistor R is increased. What happens to the following quantities? (Circle the appropriate answer.) V R1 R R2 R3 x Power dissipated in R1 increases decreases stays the same x Power dissipated in R2 increases decreases stays the same x Power supplied by voltage source increases decreases stays the same x Voltage across R3 increases d e c r e a s e s s t a y s t h e s a m e 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.
