Question

an incandescent lamp is operated at 240v and the current is 0.5A. what is the resistance of the lamp?​

Answer 1

Answer:

i think answer is 480 if right please reply me

Answer 2

Answer:

The resistance of the lamp, R, calculated is $480\Omega$.

Explanation:

Given data,

The voltage of an incandescent lamp, V = $240V$

The current flowing in the incandescent lamp, I = $0.5A$

The resistance of the lamp, R =?

From the relation of voltage, current, and resistance given below; we can find out the resistance of the lamp:

• V = $IR$
• R = $\frac{V}{I}$

After putting the given values of voltage and current in the equation, we get:

• R = $\frac{240}{0.5}$
• R = $480\Omega$

Hence, the resistance of the lamp, R = $480\Omega$.
