10.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. 40b. 30c. 20d. 1011.When a battery is “short-circuited” the resistance that can dissipate the energy of the charges is:a. The load resistance on the circuitb. The external resistance in series with the batteryc. The internal resistance within the batteryd. A combination of the internal and external resistance12.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 meterb. The current will increase due to the presence of the meterc. The resistance will decrease due to the presence of the meterd. The voltage across the resistor will increase due to the presence of the meter
