Question: In a circuit with a 12V battery and a 3Ω load resistor, what is the current flowing through the load?
Options:
2A
4A
3A
1A
Correct Answer: 2A
Solution:
Using Ohm\'s law, I = V/R = 12V / 3Ω = 4A.

Questions & Step-by-Step Solutions
In a circuit with a 12V battery and a 3Ω load resistor, what is the current flowing through the load?
Step 1: Identify the voltage of the battery, which is 12V.
Step 2: Identify the resistance of the load resistor, which is 3Ω.
Step 3: Recall Ohm's law, which states that current (I) equals voltage (V) divided by resistance (R).
Step 4: Plug the values into the formula: I = V / R.
Step 5: Substitute the known values: I = 12V / 3Ω.
Step 6: Calculate the result: 12 divided by 3 equals 4.
Step 7: Conclude that the current flowing through the load is 4A.
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) of the conductor.
