Lab1: Measuring volts, current and resistance
Introduction
Taking measurements on a circuit is an essential skill when working with electronics. Even for the simplest problems usually the first checks will be similar to the following:
- is there enough voltage for the circuit to work (dead battery?)
- is there current flowing (loose connection?)
- is the current flowing what you would expect or perhaps more (short circuit?) or much less (loose connection?)
Taking measurements will also give you invaluable and often necessary insights in the working of a circuit. So, for example, to know how long your project will be running on a battery it is necessary to know how much current the circuit uses.
