Principles of Electricity Flashcards
What is coulomb the measurement off
Charge
What is joule measurement off
Energy
What is ohm the measurement
Resistance
What is volt the measurement off
Potential difference
What is watt the measurement off
Power
What is ampere the measurement off
Electric current
Which materials are insulators
Rubbers plastics and ceramics
What’s the journey of electricity
Circuit then line conductor then returns through neutral conductor
What makes electricity have greater flow
Pressure the higher it is the greater the flow
What the equation for power
Voltage x current or P= V x I or even W= V x A
How is electrical energy measured
The amount of power dissipated by a circuit and the time for which it operates
What’s the equation of energy
Power x time
How is cost measured
Number of units used x price per unit
Why does the carrying current heat up
Due to the resistance of the conductors which must be overcome
Which two requirement are necessary for an electric current to flow Ina simple circuit
A source of chemical energy and a continuous loop of a conducting material
