Question on Practical Electricity

In summary, the conversation is about a physics question regarding the consequences of touching a live wire while standing barefoot on a wet floor. The potential solutions mentioned include the formation of a complete circuit and the possibility of breaking a fuse. The person asking for help is unsure about the equations involved and thinks the answer could be either A or B. They also mention the Earth wire being attached to the metal case and question its role in the scenario. The conversation ends with a warning not to actually try touching a live wire under these conditions.

Not sure...?


The Attempt at a Solution



I believe the answer should be A or B.

I'm thinking the live and Earth wires will form a complete circuit. Since there is very low resistance, a huge current will be drawn, breaking the fuse.

...but it could be B since Earth wire is attached to metal case & now the Earth wire is connected to the live wire?

...?

Thanks in advance!

The live wire (brown) is connected to the Earth wire. What would happen if you touch a live wire when standing barefoot on a wet floor? (Do not try it!) ehild
 

Related to Question on Practical Electricity

What is electricity?

Electricity is a form of energy that is produced by the flow of electric charge. It can be harnessed and used to power various devices and appliances.

What are the different types of electricity?

There are two main types of electricity: direct current (DC) and alternating current (AC). DC flows in one direction, while AC alternates its direction periodically. There is also static electricity, which is the buildup of electric charge on the surface of objects.

How is electricity generated?

Electricity can be generated in various ways, but the most common method is through the use of generators. These machines use mechanical energy to turn a coil of wire within a magnetic field, creating an electric current.

What are some practical applications of electricity?

Electricity is used in almost every aspect of our daily lives. It powers our homes, offices, and transportation. It is also used in industries such as manufacturing, healthcare, and telecommunications.

What are some safety precautions to take when working with electricity?

When working with electricity, it is important to take precautions to avoid electric shock or other hazards. This includes wearing protective gear, ensuring that all equipment is properly insulated, and following proper safety procedures. It is also important to have a basic understanding of electrical circuits and to never work on live circuits without proper training and supervision.
