Also E=IR (Ohms law) The lower the resistance (for a fixed voltage, like 12 volts) the higher the current draw. Your 67KOhm plug isn't drawing anything at all practically speaking.
A 1 ohm plug will draw 12 amps.
A 12 ohm plug (corrosion?) will draw 1 amp
A 67KOhm plug (burnt out) will draw .000179 amps
