Question

define least count of an instrument. how Ohm's law is verified using v-i curve

Answer 1

Least count is the least value of the measurement that can be counted using the given device. The derivative of the v-i graph gives the resistance, which verifies the ohm's law.

Answer 2

Least count is the least value of the measurement that can be counted using the given device. The derivative of the v-i graph gives the resistance which verifies the ohm law.
