i went out and bought some automotive headlights, i believe they are around 80W and 100W (theres 2 flint thing..whatever you call them) inside the bulb, and i have them all wired up in parallel..how many amps am i pulling out around???
First you have to know the excat watt rating. If you parallel both, you have to add the watts, fx. 80+80 (if that's the rating). Thias will give 160 watt. Afterwards, you use the formulas above.
