Question

Calculate resistance of an electric bulb which allow 10a current when connected to ab220vpower house

Answer 1

Answer:-

$R=20\Omega$.

Given:-

I = 10A

V = 220v

To find :-

Resistance of an electric bulb.

Solution :-

Resistance :- It is the property of any material to resist the flow of electricity through itself is called resistance.

Now, From Ohm's law we have,

$\boxed{\sf{V = I. R}}$

also,

$R = \dfrac{V}{I}$

Put the given value,

$R = \dfrac{220}{10}$

$R = 22\Omega$

hence,the resistance of an electric bulb is $20\Omega$.

Current, I = 10 A

Potential difference, V = 220 V

V = I.R

Or, V = I × R

$<font color = "blue">Solve →</font color = "pink">$

V = I × R

=> R = V / I

Putting the given values here:

R = 220 V / 10 A

R = 22 Ω

Resistance of an electric bulb is 22 Ω.
