How does the power switch on a computer work?(1 point)
A. Turning the switch on causes the conductors to release electrons.
B. Turning the switch on turns on the parts that convert electrical energy to other forms.
C. Turning the switch on activates the power source to allow electrons to flow.
D. Turning the switch on completes the circuit between the power source and the load.
Electric Circuits Quick Check
1. A circuit in a home provides power to a light fixture. The homeowners want to use a compact fluorescent bulb instead of an incandescent bulb. Compact fluorescent bulbs can produce as much light as incandescent bulbs but with less energy. How is this possible?
answer: Incandescent bulbs produce other forms of energy, too, including heat.
2. The batteries of some flashlights can be charged by turning a handle. Which energy transformation is happening in this process?
Answer: kinetic to electrical to chemical
3. How does the power switch on a computer work?
Answer: Turning the switch on completes the circuit between the power source and the load.
4. What is chemical energy?
Answer: energy stored in the bonds between atoms and molecules
5. Which energy transformation occurs when you rub your hands together to warm them?
Answer: kinetic energy to thermal energy
D. Turning the switch on completes the circuit between the power source and the load. Also, it sends a secret message to the computer saying, "It's showtime, folks!"
D. Turning the switch on completes the circuit between the power source and the load.
The correct answer is D. Turning the switch on completes the circuit between the power source and the load.
When you turn on the power switch on a computer, it completes the circuit that connects the power source (such as a power outlet or a battery) to the various components inside the computer. This allows electric current (or the flow of electrons) to travel from the power source to the different parts of the computer, including the processor, memory, hard drive, and other components.
By completing the circuit, the power switch effectively enables the flow of electricity to power up the computer and allow it to perform its functions. Conversely, when you turn off the power switch, it breaks the circuit and interrupts the flow of electricity, causing the computer to shut down.
So, the power switch on a computer works by completing or breaking the circuit between the power source and the load, allowing or preventing the flow of electricity respectively.
