A component that allows current through in one direction only. In the correct direction, diodes have a threshold voltage (typically 0.6 V) above which current can flow
Diode
1 of 15
The energy supplied by a source per unit charge passing through the source, measured in volts
Electromotive force
2 of 15
A bulb consisting of a metal filament, that heats up and glows to produce light. As the filament increases in temperature, its resistance increases since the metal ions vibrate more and make it harder for the charge carriers to pass through
Filament lamp
3 of 15
Plots of current against voltage, that show how different components behave
I-V characteristics
4 of 15
A unit of electrical energy. It is usually used to measure domestic power consumption
Kilowatt-hour
5 of 15
A light sensitive semiconductor whose resistance increases when light intensity decreases
Light-dependent resistor
6 of 15
The unit of resistance
Ohm
7 of 15
A conductor for which the current flow is directly proportional to the potential difference across it, when under constant physical conditions
Ohmic conductor
8 of 15
The current and potential difference through an ohmic conductor held under constant physical conditions are directly proportional, with the constant of proportionality being resistance
Ohm's law
9 of 15
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
Potential difference
10 of 15
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
Power
11 of 15
A measure of how difficult it is for current to flow through a material
Resistance
12 of 15
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
Resistivity
13 of 15
A device that has a fixed resistance and follows Ohm's law
Resistor
14 of 15
The unit of potential difference
Volt
