Flashcards in P2.2 Controlling And Using Electric Currents Deck (12):
What do we use to measure voltage?
What happens to current in a parallel circuit?
What happens to voltage?
Current remains the same and voltage is split
What is another name for voltage?
What is resistance measured in?
What is the equation for resistance?
What is a thermistor?
A heat dependent resistor
What is a LDR
A light dependent resistor
What is a diode?
A resistor that only allows current to flow one way, so A.C does not work
Do the resistances of LDRs and thermistors go up or down as the factor increases.
The resistance decreases as the factor increases
What is the equation for power?
What do we use to measure current?
