Question

Calculate the resiatence of an electric bulb which allow a 10a current when connected to a 220v power source

Answer 1

Answer :-

$R = 22 \Omega$

Given :-

I = 10 A

V = 220 v

To find :-

The resistance of an electric bulb.

Solution:-

Resistance →The property of an object to resist the flow of electric current through itself is called resistance.

By using Ohm's law we have ,

$\huge \boxed{V = I R}$

Put the given value ,

→$220 = 10 \times R$

→$R = \dfrac{220}{10}$

→$R = 22 \Omega$

Hence,

The resistance of the electric bulb will be $22 \Omega$.

Answer 2

$\huge\sf\underline{Answers}$

$\bf\huge\boxed{R=22\:ohm}$

Explanation—

-----------------------------------------------

Given,

Current(I) = 10 A

Potential Difference(V) = 220 V

To Find—

Resistance(R) =?

-------------------------------------------------

We know, by ohms law

V=IR

R = V/I

R= 220/10

R= 22 ohm.

Therefore the resistance of electric bulb is 22 ohm
