Question

The current flowing through a resistor connected in an electrical circuit and the potential difference developed across its ends are shown in the given diagrams
The value of resistance of the resistor in ohms is___

• A. $25$
• B. $20$
• C. $15$
• D. $10$

Answer 1

The correct option is D $10$

Given

$I=180mA=180/1000=0.18A$ and the $V=1.8V$.
So, $R=\frac{V}{I}=\frac{1.8}{0.18}=10ohms$.

Hence, the resistance in the circuit is 10 ohms.
