laws of electricity
opposite charges attract each other but like charges repel each other
what is the law of electric charges?
the study of the nature, behavior, and uses of static (stationary) electricity and related phenomena.
what is electrostatics?
1 Ω = 1 V/A
what is the formula to calculate resistance?
The process of diverting un-wanted electric charge directly into the earth
what is grounding?
The flow of electrons or other charged particles from one place to another
what is current electricity?
the total charge is the same before and after any interaction
what is the law of conservation of charge?
A circuit that contains a complete path for electrons to flow from the source of current, through the load, and back to the source
what is a closed circuit?
P=VI
what is the formula to calculate power?
the flow of current through a circuit can be controlled
what is a switch
Electricity that flows first in one direction and then the other, reversing at regular intervals
what is an alternating current?
states that the current flowing through a conductor is directly proportional to the voltage and inversely proportional to the resistance
what is Ohm's law?
Materials through which current does not easily flow
what is an insulator?
1 A= 1 C/S
what is the formula to calculate current?
SI unit for current
what is an ampere?
electricity that flows in one direction without reversing
the strength of the attraction or repulsion between two charged objects is directly related to the strength of the charges and inversely related to the square of the distance between them
what is the law of electric force?
a property that allows them to attract and repel other charged particles by the electromagnetic force
what is electric charge?
V=IR
what is Ohm's law
A material that allows current to flow through it with no resistance
what is a superconductor?
rate of charge charge flow
what is current?
a device that transforms the energy of the electric current into another useful form of energy
what is a load?
1 V= 1 J/C
what formula is used to calculate voltage?
An electrical device designed to add resistance to a circuit
what is a resistor?
the amount of energy used when 1 kW of power is used continuously for 1 hour
what is a kilowatt hour?
