Classification of Resistance
Resistance that are required to be
measured may have any value from a few micro ohms to mega ohms.
From the point of view of measurement, resistances are classified as three main
groups.
1.
Low Resistances: resistance of
the order of 1Ω or less than 1Ω.
2.
Medium Resistance: This class
includes the resistance from 1Ω upwards to about 0.1MΩ.
3.
High Resistance: Resistances
of the order of 0.1 MΩ and above are classified as high resistance.
Note: The
classification given above is not rigid, but forms a basis for techniques,
followed or measurement. Which may be different for different classes.
Different Methods used for
Measurement of Resistance are:
1.
For low Resistance Measurement:
(b) Kelvin’s
double bridge method
(c) Potentiometer
method.
2.
For Medium Resistance Measurement:
(a) Ammeter-Voltmeter
method
(b) Substitution
method
(c) Whetstone
bridge method
(d) Ohmmeter
method
3.
For High Resistance Measurement:
(a) Direct
deflection method
(b) Loss of
charge method
(c) Mega Ohm
bridge method
(d) Megger.
Thank you for sharing this helpful article we hope listen you more ahead and I want to share information about weighing industryeleweigh
ReplyDeleteHello everyone, I'm Patricia Sherman in Oklahoma USA right now. I would like to share with you my experience of borrowing USD $185,000.00 to clear my bank draft and start a new business. It all started when I lost my house and I took my stuff because of the bank policy and I met some bills and some personal needs. So I became very desperate and started looking for funds in every way. Fortunately for me, a friend of mine, Linda told me about a credit company firm, I was intrigued by the fraud, but I was intrigued by my situation and had no choice but to get advice from my friend about this company. contacting them really doubted me because of my past experience with online lenders, did you know that little? '' Elegantloanfirm@hotmail.com This company has been very helpful to me and my colleague and today, thanks to this credit company, the proud owner of well-organized work and responsibilities, they smiled back at me. So if you really need to grow or start your own business, or if you really need to borrow money in any financial hardship, we recommend you find a financial development opportunity in your business today. {E-mail:} Elegantloanfirm@hotmail.com / whats-app number +393511617486.... online for credit not a victim of scam Thank you.
