Question: If the current flowing through a resistor is 2A and the voltage across it is 6V, what is the resistance? (2022)

Options:

Correct Answer: 3Ω

Exam Year: 2022

Solution:

Using Ohm\'s Law, R = V / I = 6V / 2A = 3Ω.

If the current flowing through a resistor is 2A and the voltage across it is 6V, what is the resistance? (2022)

If the current flowing through a resistor is 2A and the voltage across it is 6V, what is the resistance? (2022)

Step 1: Identify the values given in the problem. We have a current (I) of 2A and a voltage (V) of 6V.
Step 2: Recall Ohm's Law, which states that Resistance (R) is equal to Voltage (V) divided by Current (I). The formula is R = V / I.
Step 3: Substitute the values into the formula. Replace V with 6V and I with 2A: R = 6V / 2A.
Step 4: Perform the division. Calculate 6 divided by 2, which equals 3.
Step 5: Write down the result. The resistance (R) is 3 ohms (Ω).

Ohm's Law – Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). It is expressed as V = I * R.
