Question

Consider the two circuits depicted above. The voltage source is the adjustable power supply similar to the one used in lab. The solenoid is considered to be ideal so that it has no internal resistance. The resistors in both circuits are the same: 5.0 Ohm. Consider the following scenarios:

1.The voltage of each power supply is increased at identical rates. While the voltages are being increased, which of the following is true about the currents through the power supplies?(Explain your reasoning)

a)Ileft greater than Iright

b)Ileft less than Iright

c)Ileft less than Iright

2.The voltage is kept at 5.0 V for a long time. While the voltages are held constant, which of the following is true about the currents through the power supplies?(Explain your reasoning)

a)Ileft greater than Iright

b)Ileft less than Iright

c)Ileft less than Iright

3.The voltage of each power supply is then decreased at identical rates. While the voltages are being decreased, which of the following is true about the currents through the power supplies?(Explain your reasoning)

a)Ileft greater than Iright

b)Ileft less than Iright

c)Ileft less than Iright
