In an electric circuit, various components play crucial roles in controlling the flow of electricity. Let's take a closer look at three essential circuit components:

1. Resistors: These components are used to regulate the flow of current by providing resistance to the circuit. Resistors are marked with specific resistance values, usually measured in ohms (Ω).

2. Capacitors: Capacitors store and release electrical energy in a circuit. They consist of two conductive plates separated by an insulating material. Capacitors can be used for various purposes, such as smoothing voltage fluctuations or storing energy.

3. Switches: Switches control the flow of electricity by either completing or breaking the circuit. They enable us to turn devices on or off and are often represented by the symbol 'S' in circuit diagrams.

It's essential to take certain precautions when working with electric circuits to ensure safety:

• Always disconnect the power source before making any changes to the circuit.
• Use proper insulation and avoid contact between exposed conductive parts and yourself.
• Be aware of potentially hazardous conditions, such as bare wires or damaged components, and address them promptly.

Understanding these components and practicing safety measures will enable you to work confidently with electric circuits.
