To determine the circuit's current, use the Ohm's law equation:
V = I × R
V =  Voltage
I =  Current
R =  Resistance 
Step 1: Determine the total resistance in a series
The total resistance in a series is the sum of all resistances.

I = V / R
Insert the values into the equation
I = 120 / 200
I = 0.3 A
