Question

Name different methods of finding unknown resistance

Answer 1

#R=V/I(OHMS LAW)
#R=p I/A
#Rs=R1+R2+R3...........(IN SERIES)
#1/Rp=1/R1+1/R2+1/R3..........(IN PARALLEL)

Answer 2

We can classify the resistance in the following way :

Classification of Reistance :
low resistance=0.1ohm to 1 ohm

medium resistance =1ohm to low mega ohm

high resistance=0.1 megaohm to a higher range.

Different methods of finding Unknown resistance  are based on type of resistance used:

Methods for finding
 
Low resistance:
Kelvin double bridge
Ammeter -voltmeter 

Resistance For medium Resistance:
Ammeter -voltmeter method
Wheat stone bridge method
ohm meter method

Method for finding high Resistance:
Direct deflection method
loss of charge method
Megha Ohm bridge method
