What else can I help you with?
When a flows in a wire a compass needle near the wire will move?
The wire will move due to magnetic forces got from the compass needle since its a good conductor of electricity.
What is the condition that is necessary for a charge to move in a wire?
The necessary condition for a charge to move in a wire is the presence of an electric field, which exerts a force on the charge causing it to move. This movement of charges in a wire is what constitutes an electric current.
What is inside a generator that makes electricity?
Coils of wire and a magnet. When magnetic lines of force move across a wire, it causes electrons in the wire to move. Those moving electrons are electrical current. In a generator, either the magnet or the coils of wire spin.
When a magnetic field is used to create an electric current in a wire?
The magnetic field must be changing relative to the conductor (wire). So the wire could move through the field, or the field could move past the wire, or you could have a changing field (from an electromagnet with varying current).
Which wire would have the least resitance a large diameter or small diameter wire and why?
large diameter wire simply because it will move easier Technically they would have the same resistance, but the larger diameter wire would allow more current to flow as it would have more room to move.
How do you make current?
Move the wire through a magnetic field
What must move in a coil of wire to make electricity?
A conductor
What is needed in order for electricity to move from the source to a hairdryer?
A wire.
Car shut down after open AC?
look under the hood and rev. your engine the piece that moves is the throttle on the throttle there is a wire you need to take the wire and move it back so there is more wire exposed just grab the wire with a clamp and move the throttle up and you should be fine.
You are attempting to help a person who is in contact with a hot wire your 1st step is to?
Ensure that the person is not in direct contact with the hot wire, as they could be at risk of electric shock. Encourage them to move away from the wire if they can do so safely. If the person is unable to move, turn off the power source or use a non-conductive object to carefully move the wire away from them.
How do you transfer 40kph mechanicall energy into electrical energy?
The usual method to convert mechanical energy into electrical energy is to move a wire in a magnetic field (or alternately, move the magnet near to a wire).
What two things are needed to make electrons move along a wire?
To make electrons move along a wire, a source of electrical voltage (such as a battery or power supply) is needed to provide the push or force for the electrons to move. Additionally, there must be a closed circuit or path for the electrons to flow through, typically provided by a conductor like a metal wire.
