Question

How much curaent will electric bulb
om a 220V source if the resistan
of the bulb filament
is 1200 Ohm?​

Answer 1

Answer:

V = 220 V

R = 1200 Ω

V = IR

So I = V/R

I = 220/1200

I = 0.2 A

Answer 2

0.183 A

Explanation:

$current = voltage \div resistene \\ here \\ voltage = 220 \\ resistance = 1200 \\ then \: v \div r \\ 220 \div 1200 \\ = 0.183333333333ampear \\ therefore \: the \: required \: answer \: is \: 0.183$
