Question

Seven identical lamps of resistance 220 Ω each are connected to a 220 V line as shown in
figure. Then reading of ammeter will be. Diagram for question​

Answer 1

pls refer the attachment first before for better understanding

on the left side of the ammeter 2 bulbs are connected in parallel

so the net resistance will be

220/2=110ohm

on the right side of the ammeter 5 bulbs are connected in parallel

net resistance

220/5 = 44 ohm

now if look at the circuit diagram (attachment)

you will see that the reading of the ammeter; s only due tho the current flowing through the R/5 resistance hence

I = V /R

I = 220 /44

I = 10/2

I =5 A

the answer is none of these
