Question

A lamp draws a current of 0.5A when it connected to 60Vsource what is the resistance of the lamp​?

Answer 1

Answer:

The resistance of the lamp is 120 Ω.

Explanation:

Given:

Current, I = 0.5 Ampere

Voltage, V = 60 Volt

To Calculate:

Find the resistance of the lamp = ?

Solution:

To find the resistance of the lamp = ?

$\qquad{\large{\red{\bf V \ = \ IR}}}$

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

$\quad$ Where,

• V = Voltage
• I = Current
• R = Resistance

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

$\quad \longrightarrow R \ = \ \dfrac{60}{0.5}$

$\quad \longrightarrow R \ = \ 120 Ω$

$\therefore$ The resistance of the lamp is 120 Ω.
