Question: A circuit has a total voltage of 12V and a total resistance of 3 ohms. What is the total current in the circuit?
Options:
4 A
3 A
2 A
1 A
Correct Answer: 4 A
Solution:
Using Ohm\'s Law, I = V/R. Here, I = 12V / 3Ω = 4 A.

Questions & Step-by-Step Solutions
A circuit has a total voltage of 12V and a total resistance of 3 ohms. What is the total current in the circuit?
Step 1: Identify the total voltage in the circuit, which is given as 12V.
Step 2: Identify the total resistance in the circuit, which is given as 3 ohms.
Step 3: Recall Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R).
Step 4: Substitute the values into the formula: I = V / R.
Step 5: Calculate the current: I = 12V / 3Ω.
Step 6: Perform the division: 12 divided by 3 equals 4.
Step 7: Conclude that the total current in the circuit is 4 A.
Ohm's Law – Ohm's Law states that the current (I) in a circuit is directly proportional to the voltage (V) and inversely proportional to the resistance (R), expressed as I = V/R.
