Across
- 2. Calculated by dividing potential difference by current ($V = I \times R$).
- 6. A resistor whose resistance decreases as the temperature increases.
- 9. A component that allows current to flow in one direction only
- 10. This component measures curreWATT: The unit of power, equivalent to one joule per second.
- 11. The unit of power, equivalent to one joule per second.
- 12. The unit used to measure electrical charge.
Down
- 1. A circuit loop where the current is the same at all points.
- 3. A component whose resistance decreases as light intensity increases.
- 4. A circuit with branches where the total current is the sum of the current through each branch.
- 5. and is always connected in series.
- 7. DIFFERENCE: Often called voltage, it is the energy transferred per unit of charge.
- 8. The unit of electrical resistance.
