A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. PSU is a output device because it is outputting power to the rest of the device. Most personal computers can be plugged into standard electrical outlets.

Is ups input or output device?

UPS is Uninterruptable Power Supply. It is neither input not output. It supplies electrical power to a computer when the main electrical supply is interrupted. It does not handle data in any way.

Output - because it is outputting power to the rest of the device


Is a wireless repeater an input or an output device?

It can be classified as both. It receives output from one device. It boosts the power and sends it as input to another device.


Is a chassis input or output device?

A chassis is neither an input nor an output device; it is actually a structural framework that houses and supports various computer components, such as the motherboard, power supply, and storage devices. It provides the necessary protection and organization for these components but does not directly interact with data input or output processes.


Is a power button a input device?

A input device is when you put something into the computer. A output device is when something from a computer comes out, either a hard or soft copy. So, I think it would be a input device, because you are putting a direction to turn on!


Why power supply an output device?

because it is devices


What does input volts and output volts mean?

The terminology would typically reference a device such as a power supply, charger, diverter or transformer. The Input Voltage is the voltage supplied to the device to make it work. The Output Voltage is what the device supplies to an application. For example, a power supply for a laptop might convert 120 VAC to a voltage like 19.5 volts (A Sony Laptop) for charging a laptop battery.


How efficiency of linear regulated power supply calculated?

The efficiency of a linear regulated power supply is calculated by dividing the output power by the input power and multiplying by 100 to express it as a percentage. The output power is determined by the product of the output voltage and output current, while the input power is the product of the input voltage and input current. The formula can be expressed as: [ \text{Efficiency} (%) = \left( \frac{\text{Output Power}}{\text{Input Power}} \right) \times 100 ] Due to the inherent voltage drop across the regulator, linear power supplies typically have lower efficiency, especially when there is a significant difference between input and output voltages.


What is efficiency of a transformer?

Just like any other device . . . Output power/Input power


How do you view output voltage of the power supply?

by d way input only


How do you find the efficiency of an electrical device?

To find the efficiency of an electrical device, you can use the formula: Efficiency (%) = (Output Power / Input Power) × 100. Measure the input power, typically in watts, that the device consumes and the useful output power it provides. Efficiency indicates how well the device converts electrical energy into useful work, with higher percentages indicating better performance.


Is a battery input or output?

Neither, it is a power source providing the energy to make the device work.
