Question

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

Answer 1

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

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

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

$\bf{ \underline{To \:  Find :- }}$

$\sf• \: The  \: Resistance.$

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

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

$\rightarrow  \sf R = \frac{9}{18}$

$\rightarrow  \sf R = \frac{1}{2}$

$\rightarrow  \sf R = 0.5$

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

Answer 2

Answer:

R =I/V

R =18/9

R =2ohms

Explanation:

resistance is equal to current by voltage
