Question

A 9 V battery produces a current of 18 amps. What is the resistance?

Answer 1

$\bf{ \underline{Given:- }}$

$\sf• \: Battery \: Voltage \: (V) = 9 \: v$

$\sf• \: Current \: (I) = 18 \: Amps.$

$\bf{ \underline{To \: Find :- }}$

$\sf• \: The \: Resistance.$

$\huge\bf{ \underline{Solution :- }}$

$\bf \red{ \bigstar{ \: Formula \: of \: Resistance \: (R) = \frac{V}{I}}}$

$\rightarrow \sf R = \frac{9}{18}$

$\rightarrow \sf R = \frac{1}{2}$

$\rightarrow \sf R = 0.5$

$\bf \purple{Therefore, \: the \: \: resistance \: \: is \: \: 0.5 \: Ω \: .}$
