Using a Multimeter
Measuring Voltage
To measure voltage on a battery.This is an example of a 1.4 AA battery.
- black goes to the negative and red to the positive or knobbley end.
- make sure black lead is in COM on the multimeter
- make sure red lead is in V on the multimeter
- connecting in correctly will result in a negative number
- the numbers in the V section are the range in mA.
- using the 200mA will result in 1364 or 1.364 Volts
Measuring Circuit
Below we have a circuit with a battery, resister and LED.
Here would be the circuit diagram.
