Question

A lamp dries a current of 0.5 A when it is connected to a 60 v source.what is the resistance of the lamp?

Answer 1

Answer:

120 ohm

Explanation:

Given,

v=60v

I= 0.5A

By ohm's law

V= IR

R= V/I

= 60/0.5  

=120 ohm

Answer 2

$\huge\underline{\underline{\bf\bigstar ANSWER \bigstar }}$

Given ,

➣ Current , I = 0.5 A

➣ Voltage , V = 60 V

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

According to Ohm's law ,

 ➠  V = IR

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

            $\sf = \dfrac{60}{0.5}$

            $\bf = 120$

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

➯ Resistance of the lamp = 120 Ω
