Question

Find out the current flowing through the resistor of $40\Omega$ in a closed circuit with $20$ volts across it.

• A. $0.5A$
• B. $2A$
• C. $20A$
• D. $80A$
• E. $800A$

Answer 1

The correct option is A $0.5A$

Given : $R=40\Omega$ $V=20$ volts

$\therefore$ Current flowing $I=\frac{V}{R}=\frac{20}{40}=0.5$ A
