Question

A battery of 12 volt is connected to a series combination of resistors 3 ohm 4 ohm 5 mm mm 12. How much current will flow through the 12 ohm resistor

Answer 1

Total resistance

3+4+5+12 = 24 Ω

R = V/I

24 = 12/I

I = 12/24 = 1/2 = 0.5 A

So we know that current flowing in series is same in every resistor

so the current flow through the resistor of 12 ohm will be 0.25 ohm.
