Three resistors are connected in series. What is the total resistance in the circuit if the current that flows through the wires is 2.0 A and the voltage provided by the battery is 12 V?
Assume the resistors in the above problem are replaced with light bulbs. Which of the following circuit modifications will cause the light bulbs to be brighter?
a. Rewire the light bulbs so that they are in parallel instead of in series
b. Decrease the resistance of the light bulbs
c. Increase the voltage supplied by the battery by adding a battery
d. All of the above choices are correct
