Question 356Electricity/Electronics - QMED70% to pass
A battery is connected to a circuit containing three resistors in parallel. The values of the three resistors are 2 ohms, 3 ohms, and 6 ohms. What is the voltage of the battery if the total circuit current is 12 amps?
AI Explanation
The correct answer is C) 12 volts.
The total current in a parallel circuit is the sum of the currents through each resistor. Since the total current is 12 amps and the resistor values are 2 ohms, 3 ohms, and 6 ohms, we can use Ohm's law (V = IR) to calculate the voltage of the battery. The voltage will be the same across all resistors in a parallel circuit, so the voltage is 12 amps * (2 ohms + 3 ohms + 6 ohms) = 12 volts.
The other options are incorrect because 2 volts is too low, 6 volts is too low, and 24 volts is too high based on the given information and Ohm's law.
