Answer:
<u>diode</u>: It passes current only in one direction.
<u>resistor</u>: Is the most commonly used electronic element. It is used to limit the electric current flowing in the electronic system.
<u>transistor</u>: It strengthens the current in the receivers, it can also turn it on and off. This element has three tips, which we call the base, collector and emitter.
<u>capacitor</u> : Has the ability to store electricity and can release it when needed. Next to the resistor, it belongs to the most commonly used elements in electronic devices.
Explanation:
Diode is a substance which is half conductor and half insulator that is used to compel the current to flow in only one direction. Resistor is a device which is used for controlling flow of current through circuit. Capacitor is a device which is used as a storage device which provides extra electricity to machine when it is required. Transistor is a device which is used to amplify or switch electronic signals and electrical power.
