Question

An electrical bulb is rated $40$ W - $220$ V, when it is connected to a $220$ V source. Find the current drawn by the bulb?

• A. $0.1666$A
• B. $0.1333$A
• C. $0.1623$ A
• D. $0.1818$A

Answer 1

The correct option is D $0.1818$A

We know that power is given by $P=VI$

$⟹I=\frac{P}{V}=\frac{40}{220}$

$⟹I=0.1818A$

Answer-(D)
