Question

A resistor of 80 $\Omega$ is connected to a cell and the potential difference across the resistor is 40 V. Then the amount of current that flows through the given resistor is ____A.

• A. 0.25
• B. 0.5
• C. 5
• D. 2.5

Answer 1

The correct option is B 0.5

From Ohm's Law we know that-

$V=IR$

$⟹I=\frac{V}{R}=\frac{40}{80}$

$⟹I=0.5A$

Answer-(B)
