Electricity 9 Flashcards
List the laws of static charge
Like charges repel
Opposites attracts
Neutral attracted to charged objects
What are two kinds of charge?
Positive (losing electrons)
Negative (gaining electrons)
What are conductors and insulators
Conductor: Allow electrons to easily flow through them
Insulators: doesn’t allow electrons to flow
What is static electricity?
A stored electrical charge on insulator
What is current electricity?
Charges in motion, like in circuits
What is the unit for electrical charge?
Coulomb
What would be the charge of a neutral object that gains electrons?
Negative
What would be the charge on a neutral object that loses electrons?
Positive
What is the function of a voltmeter and ammeter?
Measure potential difference or voltage in a circuit
It measures how much current is flowing or amps
What is voltage?
Electrical potential difference
What is a load?
Turns electrical energy to other types of energy
What is an electrochemical cell
Turning chemical energy into electric energy
What is the difference between a wet and dry cell?
Wet: liquid electrolyte
Dry: paste
What is a resistor?
Electrical component with a specific amount of resistance
What is resistance?
Anything in a circuit that slows the flow of electrons
