Question

A lamp of resistance 80 draw a current of 0.75A. Find the line voltage.

Answer 1

Answer:

Given, resistance (r) =80 ohm

current (I) =0.75A

according to the ohm's law (r =v/I)

on Substituting the values, we get

80=v/0.75

v= 80 *0.75

v=60 V

Answer 2

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

$\sf{resistnance = 80ohm}$

$\sf{current = 0.75ampere}$

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

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

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

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

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

$\sf{Placing \: Values}$

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

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

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