What energy change that take place when you turn on a computer?

When you turn on a computer, electrical energy from the power source is converted into various forms of energy. Most notably, it is transformed into thermal energy (heat) as components like the CPU and power supply generate heat during operation. Additionally, electrical energy is converted into light energy for display screens and sound energy for speakers. Overall, the computer's operation involves the conversion of electrical energy into multiple forms to facilitate processing and user interaction.
