1
Q
What is Ohms Law?
A
For a metallic conductor kept at constant temperature, the current in the wire is directly proportional to the potential difference across its ends.
2
Q
What is the definition of an Ohm?
A
The Ohm is defined as the resistance of a component when a potential difference of 1V is produced per ampere of current.
3
Q
What is the definition of Resistance?
A
Resistance is a measure of how much a component opposes the flow of electric current.
Or
Resistance is the ratio of the potential difference across a component to the current flowing through it.
