Question: If a circuit has a voltage of 24V and a current of 3A, what is the resistance? (2022)
Options:
4Ω
6Ω
8Ω
12Ω
Correct Answer: 6Ω
Exam Year: 2022
Solution:
Using Ohm\'s Law, R = V / I = 24V / 3A = 8Ω.

Questions & Step-by-Step Solutions
If a circuit has a voltage of 24V and a current of 3A, what is the resistance? (2022)
Step 1: Understand that we need to find the resistance (R) in the circuit.
Step 2: Remember Ohm's Law, which states that R = V / I, where V is voltage and I is current.
Step 3: Identify the values given: Voltage (V) is 24 volts and Current (I) is 3 amperes.
Step 4: Plug the values into the formula: R = 24V / 3A.
Step 5: Perform the division: 24 divided by 3 equals 8.
Step 6: Conclude that the resistance (R) is 8 ohms (Ω).
Ohm's Law – Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance.
