Question

describe four major effect of current​

Answer 1

Answer:

The four major effects are:

• heating
• magnetism
• chemical
• physiological

Heating

When current flows in a conductor, heat is produced. This heat is produced because of the resistance of the conductor. The higher the resistance the greater the heat produced.

This heating effect is used in:

electric stoves

electric radiators

electric kettles

electric cooking appliances

Magnetism

Another useful effect of electric current is the magnet effect. This effect is probably the most useful of the common effects.

There are many uses such as electric motors and electrical appliances.

Magnet

Some other magnet effects are:

TV

Radio

Transformers

Relays

Floppy disks

Chemical

Current will flow in an electrolyte solution such as salt water. If two copper electrodes are placed in an electrolyte, current will flow through the liquid. This effect can be used in electroplating to coat a metal object such as a car bumper bar.

Electrodes in electrolyte

Other examples of chemical effect are:

battery charging

electrolysis

Physiological

The physiological effect is the result of current passing through a living being such as a human. The obvious effect from this is an electric shock. An electric shock can cause severe burns or even death.

Some uses for the physiological effect are:

cattle prods

electric fences

defibrillators

electric chair
