A light sensitive semiconductor whose resistance increases when light intensity decreases
Back
Card 7
Front
The unit of resistance
Back
Card 8
Front
A conductor for which the current flow is directly proportional to the potential difference across it, when under constant physical conditions
Back
Card 9
Front
The current and potential difference through an ohmic conductor held under constant physical conditions are directly proportional, with the constant of proportionality being resistance
Back
Card 10
Front
The difference in electrical potential between two points in a circuit. It is also the work done per coulomb to move a charge from the lower potential point to the higher potential point. It is measured in volts
Back
Card 11
Front
The rate of energy transfer in a circuit. It can be calculated as the product of the current and the potential difference between two points. It is measured in watts
Back
Card 12
Front
A measure of how difficult it is for current to flow through a material
Back
Card 13
Front
A measure of how difficult it is for charge to travel through a material. It is proportional to the object's resistance and cross-sectional area, and inversely proportional to the object's length. It is measured in Ohm metres
Back
Card 14
Front
A device that has a fixed resistance and follows Ohm's law
