Question

In a circuit, if you double the voltage but keep the resistance exactly the same, what happens to the power measured in watts?

Accepted Answer

If you double the voltage, the power becomes four times higher. Voltage is the electrical pressure that pushes power through a wire, while resistance is how much the wire fights that push. The rule for power is that it equals the voltage squared, which means voltage times itself, divided by the resistance. Because you are doubling the voltage, you are essentially multiplying that pressure by two, and then multiplying it by two again because of how the math works. Think of it like a garden hose: if you double the water pressure, you get twice as much water pushing through, but it also comes out with twice the speed, which adds up to four times the total energy hitting the target.
