ELECTRICITY Flashcards
What are unbalanced charges?
A more correct term for static electricity
What does resistor mean?
Used to represent one of many different bands in a circuit diagram
What are insulators?
Any material on which the charge stays on the spot where the object is rubbed
What does discharge mean
Static charging
What is a galvanometer
An instrument used to measure very week currents
What is a switch used for
It is used to open or close a circuit to control the flow of current through it
What is a volt
Standard unit for voltage
What is an ohm
Standard unit for resistance
What is a conductor
Materials that allow charge to move freely
What does circuit mean?
Something that lets electric current pass through.
What is resistance
The property of a substance that hinders the motions of electric charge and converts it into electric energy
What is voltage?
A common term referring to potential difference
What is an ampere
The unit to measure electric current (A)
What is a battery
A combination of cells either wet or dry
What is a super conductor?
A material that offers little or no resistance to the flow of charge
What is an ohmmeter
An instrument that directly measured resistance
What is a voltmeter
The instrument used to measure voltage
What is potential difference
The difference in potential energy per unit of charge between one point on the circuit and another point on the circuit
What is a load
Items along a circuit that converts electricity into other forms of energy
