Resistors
Ohm
The ohm is the unit of electrical resistance in the International System of Units (SI). It is named after German physicist Georg Ohm
Conductor
A conductor, or electrical conductor, is a substance or material that allows electricity to flow through it
Equivalent reseistance
he equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated.
Alternating currents
Alternating Current (AC) is a type of electrical current, in which the direction of the flow of electrons switches back and forth at regular intervals or cycles.
Ampere
The ampere often shortened to amp, is the unit of electric current in the International System of Units
Insulator
Materials that do not allow electricity to pass through them are called insulators. Insulators oppose electric current and so they are used as a protection from the dangerous effects of electricity. Examples of insulators are glass, air, wood, plastic and rubber.
Transformers
Transformer, device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing
Electromagnet
Series circuit
What is a series circuit? In a series circuit, which is also known as a series connection, the circuit elements are arranged in a single path. This means that, if there are three resistors in series, the same current must flow through all 3. In a series circuit, the current is the same in all three resistors.
Power
In physics, power is the amount of energy transferred or converted per unit time.
Potential difference
Potential difference is the energy used between two points in a circuit, therefore it is measured between two points either side of a component.
Electromagnetic induction
What is magenetic poles
magnetic pole, region at each end of a magnet where the external magnetic field is strongest.
Parallel circuit
"A parallel circuit has two or more paths for current to flow through.
Voltage
Voltage describes the “pressure” that pushes electricity.
Motor
a power unit that converts electrical energy into mechanical energy, usually rotation
What is direct current
electrical current which flows consistently in one direction
What is a magentic domain
A magnetic domain is a region within a magnetic material in which the magnetization is in a uniform direction.
Induction
Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field.
Resistor
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.
Generator
a mechanical device that converts mechanical energy into electrical energy.
What is a electric field
An electric field is an invisible force field created by the attraction and repulsion of electrical charges
what is a magnetic field
The magnetic field is the area around a magnet in which the effect of magnetism is felt.
