In which circuit will the bulb or bulbs glow brightest?
A simple circuit with one bulb and one battery
A simple circuit with one bulb and two batteries
A simple circuit with two bulbs and one battery
Bulb/bulbs will be equally bright in all the above cases
Two batteries provide a greater flow of electricity than one
Consider a simple circuit containing a battery and three identical incandescent bulbs A, B and C. Bulb A is wired in parallel with bulb B and this combination is wired in series with bulb C. What would happen to the brightness of the other two bulbs if bulb A were to burn out?
