Question

the aim of the experiment is to show the relation ship between voltage and current,write the material required steps of procedure and result of experiment​

Answer 1

♦aim... and is to show the relationship between the potential difference and current passing through a conductor .

♦material required.. you need l nichrome wire of length 0.5 metre and an ammeter ,,voltmeter , 4 cell battery of 1.5 volt each .

⏩ procedures -- 1.. set up the circuit and and use only one cell in the first step and put in voltmeter for measuring the potential difference and an ammeter for measurimg current.

2. you have to Tabulate all the reading of voltmeter and ammeter .

3. next step apply two cell in the circuit I know the value of V and I

4. repeat the activity again and again with 3 and 4 cell.

5 and lastly compare the v and i.

⏩ result--- now we have concluded that the ratio of V and I is always the same that is constant .

and this constant is our which is registor in the circuit.

So now you find that v is directly proportional to I .and this is relation of which you talking.

$\frac{v}{i } = r \: {constant}$

i hope it may help you .

so plz.. mark me as brainliest.

thanks
