Question

find the current recored by ammeater in the following circuit​

Answer 1

Answer:

since the resistors are arranged in series combination

therefore,

Rs=R1+R2+R3

Rs = 20+ 20+ 30 ohm

Rs = 50 ohm

since, V= 220V which is common in battery

so,

we know that

R=VI

I= R/V

I = 50 / 220 A

I = 4.4 A

therefore the ammeter read the current about 4.4A
