According to Kirchhoff's laws, the current in a series circuit is constant, and the total resistance can be found by adding up the individual resistances. Using Ohm's law, we can find the total resistance in the circuit to be:
R = 1000 + 2200 + 680 + 1200 = 5080 ohms
Using Ohm's law again, we can find the current in the circuit to be:
I = V/R = 2.5/5080 = 0.000492 A
Therefore, the closest answer choice is A, which is 0.015 A.
