Look at the circuit shown in the figure above. With switch S1 closed, you’re making voltage measurements with your meter. Assume that each of the four resistors has a resistance value of 100 k. You measure 3.6 V across resistor R1, 1.2 V across resistor R2, 1.2 V across resistor R3, and 2.4 V across resistor R4. What is the battery voltage in the circuit?
A. 4 V
B. 6 V
C. 10 V
D. 2 V
1. Look at the circuit shown in the figure above. With switch S1 closed and the resistance value of R1 and R2 equal, meter M1 has a current reading of 0.04 A. What will be the current readings on meter M2 and meter M3?
A. Meter M2 and meter M3 will both read 0.04 A.
B. Meter M2 will read 0.02 A, and meter M3 will read 0.02 A.
C. Meter M2 will read 0.2 A, and meter M3 will read 0.4 A.
D. Meter M2 and meter M3 will both read 0.1 A.
According to the law of demand, a demand curve:
A.Has a negative slope
B.Is a horizontal,or flat,line
C.Has a positive slope
D.Exceeds the economy’s ability to produce
