Question

Calculate the potential difference across the ends of wire of resistance 2 ohm when a current of 2,5 A passes through it​

Answer 1

Answer:

we know that , potential difference = current × resistance

V= IR

V= 2.5 × 2

V = 5V

so the potential difference across the ends of wire is 5 volt.

thankyou!

Answer 2

Answer:

given,

R=2 ohm

I¹=2A

I²=5A

According to ohm's law

v=IR. ,so

v=I¹R

v=2*2

v=4 volts (ans)

again

v=I R

v= 5*2

v=10 volts(ans)
