Ohmmeters are primarily classified into two types based on how the unknown resistance is connected within the circuit. The choice of ohmmeter depends on the expected range of resistance to be measured.
Series Ohmmeter:
- In a series ohmmeter, the unknown resistance is connected in series with the meter.
- It is used for measuring medium and high resistances.
Shunt Ohmmeter:
- In a shunt ohmmeter, the unknown resistance is connected in parallel (shunt) with the meter.
- It is used for measuring low resistances accurately.
