Practice these randomly selected questions to test your readiness.
Question 1
A 100 W light bulb is connected to a 120 V power source. What is the current flowing through the bulb?
Question 2
A circuit consists of a 10 Ω resistor, a 20 Ω resistor, and a 30 Ω resistor connected in series. If a voltage of 12 V is applied across the circuit, what is the current flowing through the circuit?
Question 3
