Electric Quantities Flashcards
What is Electricity?
A flow of electrons around a circuit
What is electric charge?
The fundamental property of electricity that constitutes an electric current when under the influence of an electric field
What is 1 Coulomb?
The amount of charge transferred by a current of 1 Ampere in 1 second
What is 1 Volt?
The potential difference between two points in a circuit in which 1 Joule is converted to other forms when 1 Coulomb of charge passes between them
What is Electromotive Force?
The work done by the source in driving a unit charge around a complete circuit
What is Terminal Potential Difference?
The potential difference across the two terminals of an electric source
What is Load Resistance?
The effective resistance against the moving charge outside the source
What is Internal Resistance?
The resistance against the moving charge in the source
What is a kilowatt-hour?
The quantity of energy converted to other forms of energy by a device of power 1 kilowatt in a time of 1 hour
What is Power?
The rate at which work is done or the rate at which energy is converted to other forms
