8.6.2.1 Ohm's Law

Ohm's law and the different ways this

equation can be set up can be seen

here.

- Current is measured in Ampere A
- Voltage is measured in Volt V

- Resistance is measured in Ohm Ω

8.6.2.2 Electrical circuits

Circuits can be simple and just consist of a single element in addition to the

power supply, which can be either DC (Direct Current) or AC (Alternating

Current).

In the examples here, it is direct voltage, and

both series and parallel connections are

shown.

Let's say we have a 9V battery and a light bulb

with 18Ω. Then you can try to see if you can

calculate the values.

Note that the resistance in the series
connection must be added together, but in a

parallel connection the method is:
