Question

2. A fluorescent tube is marked 40 W, 220
What current is flowing through it when
being operated?​

Answer 1

Answer:

Power = 40 W

Voltage = 220 V

Since P = VI or

I = P/V = 40/220 =2/11 A

Answer 2

$\huge \boxed{ \underline{ \bf{ \green{ANSWER}}}}$

I = p/v

I = 40/ 220

I = 2/ 11 Ampere.
