What is the main purpose of the grounding pin on a three prong plug for an appliance?
Mainly to prevent electrical shocks to the user of the appliance. Also helps keep the appliance from being damaged. <><><> The purpose of the grounding pin or prong is to connect the metal casing and any metal parts inside the appliance straight back to ground independently to the neutral wire. Then, if ever the metal casing or any metal parts inside the appliance become electrically "hot" or "live" because of an equipment failure, accidental damage - or some other cause of a malfunction - the direct path back to ground will in effect produce an immediate short circuit that will make the fuse or circuit breaker, that is protecting the circuit supplying current to the appliance, to operate to break the supply of current. By doing so, it helps to prevent electrical shocks to the user of the appliance. For more information see the answer to the Related Question shown below.
What are the two things needed to make current flow in electricity?
A flow of electrons is needed to have a current. And there (usually) must be a complete circuit. And you need a voltage to make the current move around your circuit. All tied up in Ohms Law - which I'll leave to you.
What must pass through a coil in order to make an electromagnet?
An electrical current will cause an electromagnet to energise.
What material is used to make a fuse wire?
The material suitable for making a fuse wire should have a low melting pt. so that it can easily melt and cut off the flow of current and save the electrical appliance...
Can you use aluminum wire to feed an electric range?
Yes, if the guage/current capacity is right. Make sure all the components that will connect to the wire such as outlet and breaker are approved for aluminum. Check your local electrical code to make sure it's allowed.
Can you make an electrical current with an electrical field?
No. only flow of current develops electrical field. whereas magnetic field can make current to flow through a closed path. Absolutely YES. I wander how radios and TV works.AnswerYes, it is an electric field that causes current to flow in a circuit.
What is an electric conductor and insulator?
An electrical insulator is a material that resists electric current, and will not allow it to flow easily. Examples include glass and most ceramics. An electrical conductor is a material that offers very little resistance to electric current, allowing it to flow freely and easily. Most metals make excellent electrical conductors.
What do you plug an electric appliance into to make it work?
socket
What can be inferred about the currentbpassing through the bulb?
We can infer that current is needed to generate Electrical appliances and also to make the flow of electric circuits be completed.
What is the difference between an electrical insulator and an electric discharge?
An electrical insulator is a material whose internal electric charges do not flow freely, and therefore make it nearly impossible to conduct an electric current under the influence of an electric field. This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily.Electric discharge in gases occurs when electric current flows through a gaseous medium due to ionisation of the gas. Depending on several factors, the discharge may radiate visible light.
What is a Current Reversing Transformer?
This is a transformer built into electrical appliance to make electricity meter to stop reading or made to read in reverse order. This reduces the consumption reading and cheats the system. That is bad.
What do you nned to make an electric current?
An electrical potential difference (aka. a difference in applied voltage), and a conductor / circuit. Electrons would help too.

Do magnets make electricity?
No. Magnets create an electric feild, not electricity.However, when you spin a magnet inside a coil of wire (or you can spin the coil of wire instead), you will create an electrical current.
How do current clamp on amp meters work?
clamp is an electrical device having two jaws which open to allow clamping around an electrical conductor. This allows properties of the electric current in the conductor to be measured, without having to make physical contact with it, or to disconnect it for insertion through the probe.
How does a speaker make sound with electric energy?
A loudspeaker contains a metal coil, known as an electromagnet, that creates a magnetic field when an electrical current passes through it. It is the action of the electromagnet that is responsible for converting electrical energy into audible sound.
