Question 356Electricity & Electronics - QMED
70% to passA 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?
A2 volts
B6 volts
C12 volts
D24 volts
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.
