Step-by-step solution for: Electric Circuits Worksheets | Types, Ohms Law, Hazards, Safety
Let's analyze each situation step by step and determine whether the action should be continued or avoided, along with an explanation for each decision.

Nishie warns his friends to not plug too many devices into a singular socket inside their home.
- Action: Avoid
- Explanation: Plugging too many devices into a single socket can overload the circuit, leading to overheating of wires, which may cause fires or damage to the appliances. It is safer to distribute devices across multiple sockets or use power strips designed for such purposes.
---
Bill's friend suffered an electric shock with a live wire, and he decides to pick him up quickly to save him.
- Action: Avoid
- Explanation: Touching someone who is experiencing an electric shock while they are still in contact with the live wire can result in the rescuer also getting shocked. The correct procedure is to first turn off the power source or use a non-conductive material (like a dry wooden stick) to separate the person from the live wire before attempting to help.

Whenever their city experiences a blackout, Martes turns off all her appliances from the circuit breaker of their home.
- Action: Continue
- Explanation: Turning off appliances during a blackout prevents potential damage when the power is restored suddenly. This sudden surge of electricity can harm sensitive electronic devices. Additionally, it ensures safety by reducing the risk of overloading circuits when power is reinstated.
---
Gem has a habit of getting herself completely dry before working with electricity.
- Action: Continue
- Explanation: Water is a good conductor of electricity, so being wet increases the risk of electric shock. Ensuring that one is completely dry before working with electrical appliances or wiring minimizes the chances of accidents.

Louis keeps his cell phone turned on inside the car while being filled with petrol inside a gas station.
- Action: Avoid
- Explanation: Using electronic devices like cell phones near fuel sources (such as at a gas station) can create sparks, which may ignite the fuel vapor and lead to explosions. It is crucial to turn off electronic devices to avoid such hazards.
