Across

1. ..is simply the inverse of Resistivity (G) = 1 / ρ (12)
6. are semi-conductors only allow charge one way, forward bias. (Most have a 0.6V threshold potiental) (6)
7. P= I V Note: 1 Watt= 1 Joule per 1 second (5, 2)
8. changes the potential difference and current. (Variable power supply will also do this) (1, 8, 8)
10. allows a change of volts supplied from the battery source. (1, 13)

Down

2. The rate of flow of charge (A, Amperes) I= Q / t (7, 1)
3. has a negative temperature coefficient. This is because as it warms up more energy carriers become available to carry charge. (1, 10)
4. Reciprocal of resistance, measured in Siemens (S). G= I / V (11, 1, 2)
5. ...states as long as temperature and physical conditions stay the same. Current is directly proportional to Potential Difference. (4, 3)
9. PD= WD (J) / Q (C) (9, 10, 1)
