Question

How much current will electric heater coil draw from a 220 volt line,if the resistance of the heater coil is 40 ?

Answer 1

$\textsf{Since we know formula which say}$

$\huge{\Longrightarrow{\boxed{\bold{R = \frac{V}{i}}}}}$

$\textsf{\underline{Resistance is 40 Ohm}}$

$\textsf{\underline{Potential Difference is 220 V}}$

$\textbf{\huge{Note:}}$

$\textsf{Unit of current is Ampere (A)}$

$\huge{\textbf{\underline{Solution}:}}$

$\textsf{On applying formula we get}$

$\mathsf{40 = \frac{220}{i}} \\ \\ \mathsf{i = \frac{220}{40}} \\ \\ \mathsf{Current = 5.5\:A}$

$\texttt{Hence current of 5.5 A is drawn}$

$\huge{\boxed{\textbf{\underline{ 5.5 Ampere}}}}$

$\underline{\textsf{Thus, electric hearter will draw 5.5 A}}$

Kindly,look into attachment ^_^

The electric heater draws 5.5 Amperes of current.

Formula used

V = i/r

By Ohm’s law.

R = Resistance

They gave ,

Resistance is 40 ohm

P.D is 220V
