Question

x+y=5 2x-3y=4 by elimination method by equating the co-efficient method​

Answer 1

Answer:

Question is slightly wrong.Resistance should be 44ohms

Resistance=R=44ohms

Potential difference=V=220V

Current=I=?

Using ohms law

\boxed{\sf \dfrac{V}{I}=R}

I

V

=R

\begin{gathered}\\ \sf\longmapsto I=\dfrac{V}{R}\end{gathered}

⟼I=

R

V

\begin{gathered}\\ \sf\longmapsto I=\dfrac{220}{44}\end{gathered}

⟼I=

44

220

\begin{gathered}\\ \sf\longmapsto I=5A\end{gathered}

⟼I=5A
