Question

an electric bulb of resistance 80 ohm draws a current of 0. 75 A . find the line voltage
​

Answer 1

Answer: 60volt

Explanation:

Given values :. Resistance=80ohm

Current=0.75ampere

According to ohms law

We know V proportional to I

Therefore. V=IR

V=0.75×80volt

V=7.5×8volt

V=60volt

Answer 2

$\huge{\underline{\underline{\sf{Given-}}}}$

$\sf{resistnance = 80ohm}$

$\sf{current = 0.75ampere}$

$\huge{\underline{\underline{\sf{To \: Find-}}}}$

$\sf{voltage \: (v) = }$

$\huge{\underline{\underline{\sf{Solution-}}}}$

$\sf{we \: know \: ohm \: formula}$

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

$\sf{Placing \: Values}$

$\longrightarrow\sf{v = 80 \times 0.75}$

$\longrightarrow\sf{v = 60v}$

⛬ $\sf{The \: Voltage \: is \: 60Volt}$
