Question

Define Ohm’s law. Write its mathematical expression. Draw its Circut diagram. Draw its VI graph and what does its slope give

Answer 1

Answer:

Answer

Ohm's Law states that the ratio of potential difference(V) between any two points on a conductor to the current(I) flowing through them are constant, provided the temperature of the conductor does not change.

V/I = constant

where,

V= Potential difference in volts

I= Current in Ampere

R= Resistance of conductor between two points in ohm

∴V=I⋅R

So, V∝I, it means as voltage increase, current also incerease at a constant resistance.

Answer 2

Answer:

Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm's law is V=IR.

Explanation:

Slope of V-I graph represents the Resistance.
