ma,am, sir is their any more simpler way to understand ohm's law better. can not understand it properly

Ohm's law: According to Ohm's law "At constant temperature, the current flowing through a conductor is directly proportional to the potential difference across its ends."
If I is the current flowing through a conductor and V is the potential difference across its ends, then according to Ohm's law
or V = IR
where R is constant for a given metallic wire at a given temperature, and this constant is named resistance. It is the property of a conductor to resist the flow of charges through it.
If the potential difference across two ends of conductor is 1V and the current through it is 1A, then the resistance of the conductor is 1Ω.

- what is the unit of resistivity?
- a potential difference of 10 volt is needed to make a current of 0.02 impair for flow through a wire. what potential difference is needed to make a current of 250 mili ampere flows through the same wire
- Define resistance and also explain it through ohm law?
- potential diffrence
- define the term ohm meter
- (a) Why do copper or aluminium wires generally used for electrical transmission and distribution purposes ? (b) Two wires, one of copper and other of manganin, have equal lengths and equal resistances. Which wire is thicker ? Given that resistivity of copper is lower than that of manganin.
