Question

When the potential difference between two points is 1 volt and current through it is 1 A, then the resistance between the points is:

• A. $3\Omega$
• B. $2\Omega$
• C. $0.5\Omega$
• D. $1\Omega$

Answer 1

Answer: (D)

$1\Omega$

Given:

Potential difference $V=1volt$

Current $I=1A$

From Ohm's law, $V=IR$

$\therefore R=\frac{V}{I}=\frac{1}{1}=1ohm$
