Question

1OOW, 2OOV ke electric bulb ka current aur resistance calculate karo?​

Answer 1

$\large\underline{\underline{\sf Given:}}$

• Power (P) = 100 W

• Voltage (V) = 200 V

$\large\underline{\underline{\sf To\:Find:}}$

• Current (I) = ?

• Resistance (R) = ?

$\large\underline{\underline{\sf Solution:}}$

As we know ,

$\large{\boxed{\sf Power (P)=VI}}$

$\large\implies{\sf 100=200×I}$

$\large\implies{\sf I=\frac{100}{200} }$

$\large\implies{\sf I=0.5A}$

And ,

According to Ohm's Law :

$\large{\boxed{\sf V=IR }}$

$\large\implies{\sf 200=0.5×R }$

$\large\implies{\sf R=\dfrac{200}{0.5}}$

$\large\implies{\sf R=400 }$Ω

$\Large\underline{\underline{\sf Answer:}}$

•°•Current flow in bulb is 0.5A and Resistance of bulb is 400Ω
