Question: If a circuit has a total current of 3 A and a total resistance of 6 ohms, what is the voltage supplied by the battery?
Options:
9 V
6 V
3 V
12 V
Correct Answer: 9 V
Solution:
Using Ohm\'s law, V = I * R, we have V = 3 A * 6 ohms = 18 V.

Questions & Step-by-Step Solutions
If a circuit has a total current of 3 A and a total resistance of 6 ohms, what is the voltage supplied by the battery?
Correct Answer: 18 V
Step 1: Identify the values given in the problem. We have a total current (I) of 3 A and a total resistance (R) of 6 ohms.
Step 2: Recall Ohm's law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 3: Substitute the values into the formula: V = 3 A * 6 ohms.
Step 4: Calculate the result: 3 A * 6 ohms = 18 V.
Step 5: Conclude that the voltage supplied by the battery is 18 V.
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 resistance (R) being the constant of proportionality, expressed as V = I * R.
