Physics - Current Electricity

Question	Answer
current	the rate of flow of charge (or electrons) Amps - ammeter - in series
Voltage/potential difference	The push on the current, an electrical pressure that gives a measure of the energy transferred Volts - voltmeter - in parallel
resistance	slows/stops the flow of electrons Ohms - ohmmeter
Diode	Allows current to flow in ONE DIRECTION
LDR light dependent resistor	Decreases resistance as light intensity increases
Thermistor	Decreases resistance as temperature increases
Resistor	Keeps resistance constant
Filament Lamp	Increases resistance as temperature of filament increases
Circuit breaker/fuse	Stops the flow of electricity if current is too high
