A conductor for which the current flow is directly proportional to the potential difference across it, when under constant physical conditions (5, 9) 6. 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 (5) 8. The unit of potential difference (4) Down 2. The energy supplied by a source per unit charge passing through the source, measured in volts (13, 5) 3. The unit of resistance (3) 4. A measure of how difficult it is for current to flow through a material (10) 5. A unit of electrical energy. It is usually used to measure domestic power consumption (8, 4) 7. Plots of current against voltage, that show how different components behave (1, 1, 15) 9. A device that has a fixed resistance and follows Ohm's law (8) 10. 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 (8, 4)
