Question

the potential difference between two terminals is about 220 volts and the current flow is 2 amperes? find the resistance?

Answer 1

Dear user,
Mark the answer as brainliest if you find it useful.
Just use the Ohm's law ie, V=IR
Therefore, Resistance,R=V/I
R=220/2=110 ohm

Answer 2

The resistance between the two terminals is 110 ohms.

Given:

Potential difference = 220 volts

And current flowing between two terminals = 2 A

Solution:

Now we know that potential difference = current × resistance

That is indicated by the formula,

$\bold{V=I \times R}$

This is given by ohm’s law that states the potential difference across an ideal conductor which is directly proportional to the current through it.

So applying the values,

$220=2 \times \mathrm{R}$

R = 110 ohm

Hence the resistance between the two terminals is 110 ohms.
