types of currents
When electrons sway back and fourth in the direction of electric field.
What is alternating current
The part of circuits that provides electrons.
What is a generator?
Unit for Force that moves current energy?
What a volt?
Refers to the electrical and magnetic forces produced by an electric current.
What is an electromagnet?
Is used to step the voltage down and the power up (P=IV).
What are transformers?
When electrons flow in one direction.
What is direct current?
Part that create mechanical motion.
What is a moter?
Unit for current that runs through circuit.
What is ampere?
A vector field that surrounds magnetized objects.
What is magnetic field?
A Physical field that surrounds electrically charged particles.
What is an electric field?
When wires branch off and power light bulbs parallel to each other.
What is a parallel circuit?
Part that keeps electrons in the conductor.
What is a insulator?
The unit for a current?
What is an ohm?
A region within a magnetic material in which the magnetization s uniform in direction.
What is magnetic domain?
The difference of electrical potential between two points on a circuit.
What is Potential diffrence?
When a wire goes in a complete circle/ only one path.
What is a series circuit?
Object tat allows electrons to flow though it.
What is a condoctor?
Force that moves electrons though circuit.
What is voltage?
Points on magnet where external magnetic field is strongest.
What are magnetic poles?
When a change in magnetic field induces a voltage in a circuit.
What is induction?
V=IR
What is Ohms law?
Part that slows down electrons.
What is a resistor?
A different way of indicating 'total' resistance. (Rt)
What is equivalent resistance?
The product of an electromotive force across an electrical conductor in a changing magnetic field.
What is electromagnetic induction?
The rate at which electrical energy is supplied to a circuit.
What is power?
