Conductor of electricity

When we touch a naked current-carrying wire, we may experience an electric shock. This is because our body acts as a conductor of electricity. Let's understand why.

What is a conductor?
A conductor is a material that allows the flow of electric current through it easily. Metals such as copper and aluminum are good conductors of electricity. Our body contains a significant amount of water and various electrolytes, which makes it a conductor of electricity as well.

How does electricity flow?
Electricity is the flow of electrons through a conductor. In a current-carrying wire, electrons move from the negative terminal of a power source (such as a battery) towards the positive terminal. This movement of electrons creates an electric current.

Electric shock and our body as a conductor
When we touch a naked current-carrying wire, the electric current flows through our body. As our body is a conductor of electricity, the current passes through us. The severity of the shock depends on various factors like the voltage, current, and the path the current takes through our body.

Resistance and its role
Resistance is the property of a material that opposes the flow of electric current. In our body, the resistance to electric current flow is relatively high compared to metals. However, it is not high enough to prevent the flow of current completely. Therefore, we still experience an electric shock when touching a current-carrying wire.

Effects of electric shock
Electric shocks can cause various effects on our body, depending on the severity and duration of the shock. Mild shocks may cause a tingling sensation or muscle contractions, while severe shocks can lead to burns, injury, or even be life-threatening.

Precautions to avoid electric shocks
To avoid electric shocks, it is important to take certain precautions:
- Never touch naked or exposed wires.
- Always ensure electrical appliances and wiring are properly insulated.
- Use electrical safety devices like circuit breakers and residual current devices (RCDs).
- Seek professional help for electrical repairs or installations.

Conclusion
In conclusion, when we touch a naked current-carrying wire, we get a shock because our body acts as a conductor of electricity. The electric current flows through our body, causing the shock. It is important to take precautions to avoid such shocks and ensure electrical safety.
