Question

A potential difference of 20V appears across the ends of a resistor when 2.5A of current is passed through it.what is the resistance of the resistor
​

Answer 1

$\LARGE{ \underline{ \orange{ \sf{Required \: answer:}}}}$

here given ,

V = 10 V

I =5A

Now using ohm's law

=> V =IR

=> R =V/I =10/5 =2 ohm
