Resistance Flashcards
What is resistance measured in?
Ohms (𝛀)
What does higher resistance equal in?
Lower current and a higher temperature
What does resistance do in a series circuit?
Adds up
What does resistance do in a parallel circuit?
Decreases
What is the resistance equation?
Resistance (𝛀) = potential difference (V) / current (A)
Resistance in a wire?
As current increases so does voltage. Resistance is proportional
Resistance in a filament bulb?
Resistance increases if temperature increases
Resistance in a diode?
Forward resistance is low backward resistance is high
Resistance in a thermistor?
Resistance decreases if the temperature increases
Resistance in a LDR (light dependent resistor)?
Resistance decreases if the light intensity on it increases
