I have a physics problem that i would like to hear the solution to (i gave it a shot myself)

(heads up: english isnt my first language. and its my first time using reddit lol) the voltage at the voltmeter V is 4.5V, the amps at the ampmeter A1 is 0.3A. figure out what ampmeters A2 and A3 are reading. https://ibb.co/NnfTTZxX reddit doesnt let me put images for some reason so i hope this works. i gave it a try and after a bit of time got the solution that the amps at A2 are 0.05A and A3 is the same. (note: "P" is the switch you can ignore its existence i guess)
