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.

- To find rarional btw potential difference and current
- define ohms law
- Please find the attached question,
- How many 176 ohm resistors ( in parallel) are required to carry 5A on a 220V line?
- Why resistance will increase to 3 times when length is increased 3 times and will not increase to 9 times?
- A battery of 9V is connected in series with resistors of 0.2 ,0.3, 0.4, 0.5, and 12 . How much current would flow through the 12 resistor?
- A bulb is rated as 60W , 220V . what does it mean?
- Fig a,b,c show three cylindrical copper conductors along with their face areas and length.Compare the resistance and the resistivity of the three conductors justify your answer.Which geometry will have highest resistance and why?
- In an experiment on studying the dependence of current (i) flowing through a given resistor on the potential difference (v) applied across it, list two ways how a student would change the values of current in the circuit?
