It's the same thing... if you add resistance to a circuit you reduce the
voltage applied to any individual part of the circuit and you reduce current
going through the circuit.
If you have a coil with low resistance and you apply 12V, you get a certain
amount of current flowing through the coil. If you add a ballast resistor
into the circuit, then there is a voltage drop across the resistor and the
coil itself sees only a part of the whole 12V, and less current flows
through the whole circuit.
