Quiz Questions & Answers
Review every prompt, the correct responses, and helpful context to prep for your own run-through.
Question 1: According to Ohm's Law, how are voltage (V), current (I), and resistance (R) related?
R = V * I
I = V / R
V = I * R
V = I + R
Question 2: In a series circuit with multiple resistors, how is the total resistance calculated?
By averaging the resistances
By dividing the resistances
By adding the individual resistances
By multiplying the resistances
Question 3: What is the primary difference between alternating current (AC) and direct current (DC)?
AC is safer than DC
DC flows in one direction, AC reverses periodically
DC requires thicker wires than AC
AC flows in one direction, DC reverses
Question 4: What happens if an electrical circuit is overloaded, such as by plugging in too many high-power devices?
The voltage increases dramatically
The current drops to zero
The wires can overheat, potentially causing a fire
Resistance decreases
Question 5: In a scenario where a light bulb flickers when another appliance is turned on in the same room, what is the most likely cause?
Ground fault
Voltage drop due to shared circuit load
Insulator breakdown
A short circuit
Question 6: Is it a myth that rubber-soled shoes fully protect you from electric shock when touching a live wire?
Yes, it's a myth; they offer limited insulation but not against high voltage
No, they provide complete protection
Yes, but only for low voltage
No, but only if the shoes are new
Question 7: How is electric power (P) calculated in a simple circuit?
P = R * V
P = V / I
P = I / R
P = V * I
Question 8: What role does an insulator play in electrical applications?
It increases circuit speed
It prevents unwanted flow of current
It generates static charge
It conducts electricity efficiently
