Resistance Flashcards
1
Q
Resistance
A
A measure of the opposition to flow of charge
2
Q
Ohm
A
1 Ohm is the resistance of a component when the component has a potential difference of 1V per unit Ampere
3
Q
Ohm’s Law
A
Provided the temperature is constant, the current through an ohmic conductor is directly proportional to the potential difference across it. This means the resistance is constant
4
Q
Ohmic conductor
A
A conductor for which the potential difference is proportional to current. Obeys Ohm’s Law
5
Q
Light dependent resistor
A
An electrical component with a resistance that decreases as the light intensity incident on it increases
