Question

The potential difference between the terminals of an electric heater is 100 volt when it draws a current of 5 ampere from the source what current will the heater draw if the potential difference is increased to to 160 volt

Answer 1

$\large\pink{\mathbb{FINDING\: RESISTANCE \: OF\: HEATER}}$

$V= 100\:v$

$I = 5 \: Amp.$

$R =?$

$\huge\pink{\underline{\mathbb{USING\:FORMULA}}}$

$\huge\green{\underline{\mathbb{V= IR}}}$

$100 = 5 \times r$

${\boxed{R = 20 \: ohm}}$

$\large\pink{\underline{\mathbb{FINDING\:CURRENT\:WHEN \: POTENCIAL\: DIFFERENCE\:IS\:INCREASED}}}$

$R= 20 \: ohm$

$V = 160$

$I=?$

$\huge\pink{\underline{\mathbb{USING\:FORMULA}}}$

$\huge\green{\underline{\mathbb{V= IR}}}$

$\large{160 = I \times 20}$

$\large{I= \frac{160}{20}}$

$\huge\red{\boxed{\purple{I= 8 \: Amp.}}}$
