An electrical circuit can demonstrate energy flow even if it is missing a component due to its closed-loop structure. The energy source will push electrons through the circuit in the loop, and any missing component or gap will not stop this flow. This is because electric current flows in a closed loop, and the energy transfer can still be observed in the completed part of the circuit.
To demonstrate transformation of energy with a circuit board, you would need a power source (such as a battery), components like resistors, capacitors, and LEDs to manipulate the energy, and a multimeter to measure voltage and current. By connecting these components in a circuit, you can show how electrical energy can be transformed into different forms such as light, heat, or sound.
A light bulb in an electrical circuit transforms electrical energy into light energy and thermal energy (heat).
Electrical energy flows in a circuit, which is the movement of electrons through a conductor like a wire. This flow of electrons creates an electric current that powers devices connected in the circuit.
When a switch is closed, electrical energy is converted into other forms of energy depending on the circuit. For example, in a light bulb circuit, electrical energy is converted into light and heat energy. In an electric motor circuit, electrical energy is converted into mechanical energy.
Quite often, the word "circuit" is used for an electrical circuit. In that case, the energy is electrical energy.
