Question

The current flowing through the resistors and potential difference developed across its ends are shown in the figure. Then value of resistance is ______ Ohm

• A. 10
• B. 8
• C. 1
• D. none

Answer 1

The correct option is A 10

Given that,

Current $=I=180mA=0.180A$

Voltage $+V=1.8V$

As we know that ohm's Law relates the current flowing in a wire certain resistance with the potential difference applied across can be represented mathematically as follows:

$V=IR$

$\begin{array}{c}R=\frac{V}{R}\\ R=\frac{1.8}{0.180}\\ R=10\Omega \end{array}$

So, the value of the resistance of the wire through which current is passing is $10$ ohms.
