Which of the following instruments is typically used for measuring medium resistances?
Right Answer is:
All of the above
SOLUTION
Instruments typically used for measuring medium resistances includes Kelvin’s bridge, Wheatstone bridge, Slide wire bridge, ohmmeter and Post Office box .
- Wheatstone bridge: The Wheatstone bridge is a very important device used in the measurement of medium resistances. It is considered the most accurate method for measuring resistances.
- Kelvin’s bridge: While primarily known for measuring low resistances, the Kelvin bridge can also be adapted for some medium resistance measurements.
- Ohmmeter: Ohmmeters are electrical instruments used to measure electrical resistance, and can be used to measure medium resistances. The ammeter-voltmeter method is also suitable for measuring medium resistances.
