1

Ohm's law

Potential difference across a conductor is directly proportional to the current in the conductor at constant temperature

2

Ohmic conductor

Conductor that obeys ohms law. Resistance remains constant when voltage is varied over the resistance OR current is increased.

eg copper wire

3

Non-ohmic conductor

Does not obey ohms law. resistance is not constant when voltage is varied across it.

eg. diodes and transistors

4

Power

rate at which work is done

5

what divides voltage?

Seires circuits

6

what divides current?

Parallel circuits
