Lab4 B: Ohm’s law

Reading time: 10 mins

In this prelab, we will review the breadboard connection and Ohm’s law.

Breadboard connection is one of the most important skills to learn in the course. We started to build a circuit on a breadboard. However, there are some common mistakes in breadboard connection.

The following video has more detailed introduction about breadboard connection. If you are in a rush, at least watch this video from 3min to 8min.

Ohm’s law describes the relationship among Voltage (V or E), Resistance (R) and Current (I).  It is the foundation of the rest of course. If you know any two variables, the third one can be calculated.

The following video explains what is Ohm’s law. Please watch the first 5 min at least.

Now you can work on the quiz on Blackboard.  In your lab session, we will prove  Ohm’s law in different conditions.
