A1.5m wire carries a 3 a current when a potential difference of 84 v is applied. what is the resistance of the wire?

Resistance can be calculated using equation:

Here, V denotes voltage  

I denotes current  

R denotes resistance  

Here V is given as 84 V  

I is given as 3 A  

So by putting all the values in the equation, we will get:  

R=0.035 ohm  

So, resistance here will be 0.035 ohm .

b. is the answer hoped i
