Rather than use a fixed-rail voltage source, it’s more efficient and flexible to utilize a current source so that performance remains consistent while supply rail and coil resistance change ...

We’ll explain how to calculate resistance using the formula R=IV , where R is resistance, V is voltage, and I is current, and show how this simple equation helps us understand how resistors ...

Ensure max electric fuel pump output and safety with a relay for no voltage drop, plus an oil pressure switch that won’t let the pump run if the engine loses oil pressure.
