Determine the maximum number of 50 w/100 v light bulbs that can be connected together in parallel so as not to burn out a 15 A fuse when the bulbs are powered by a 75 v source (assume that the resistance of the fuse is negligible).

a. 40

b. 30

c. 20

d. 10

When a battery is “short-circuited” the resistance that can dissipate the energy of the charges is:

a. The load resistance on the circuit

b. The external resistance in series with the battery

c. The internal resistance within the battery

d. A combination of the internal and external resistance

Although to a very small extent, even the proper use of an ammeter has an effect on a circuit. Imagine a single loop circuit composed of a battery, a resistor and an ammeter. Which of the following is true?

a. The current will decrease due to the presence of the meter

b. The current will increase due to the presence of the meter

c. The resistance will decrease due to the presence of the meter

d. The voltage across the resistor will increase due to the presence of the meter
