Question

Consider the following parallel circuit. The voltage of the battery is 24 volts. Lamp 1 is rated at 48 watts, and lamp 2 at 72 watts. a) What is the voltage drop (loss) across lamp 1, in volts? b) What is the voltage drop (loss) across lamp 2, in volts? c) What is the current which flows through lamp 1, in amps? d) What is the current that flows through lamp 2, in amps? e) Find the resistance of lamp 1, in ohms. f) Find the resistance of lamp 2, in ohms. g) What current is flowing through the battery, in amps? h) What power is generated by the battery, in watts? i) If lamp 2 goes bad, what would be the effect on lamp 1? Explain why. j) What is meant by a short circuit, and what would be some of the consequences if one occurs? k) Answer the following i) What will be the equivalent resistance, in ohms, of a 3 ohm resistor and a 6 ohm resistor wired in parallel? ii) Which lamp will be less bright? Explain your reasoning. l) Where in real life are appliances wired in parallel as shown in the circuit above?
