Question: If a circuit has a total resistance of 12Ω and a total current of 2A, what is the total voltage supplied by the battery?
Options:
12 V
24 V
36 V
48 V
Correct Answer: 24 V
Solution:
Using Ohm\'s law, V = I * R = 2A * 12Ω = 24 V.

Questions & Step-by-Step Solutions
If a circuit has a total resistance of 12Ω and a total current of 2A, what is the total voltage supplied by the battery?
Step 1: Identify the values given in the problem. We have total resistance (R) = 12Ω and total current (I) = 2A.
Step 2: Recall Ohm's law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 3: Substitute the values into the formula: V = 2A * 12Ω.
Step 4: Calculate the result: 2 * 12 = 24.
Step 5: Conclude that the total voltage supplied by the battery is 24V.
Ohm's Law – Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, with the resistance (R) being the constant of proportionality, expressed as V = I * R.
