How does the battery trigger current

How Do Smoke Detectors Work? | NIST

They most commonly do this using two types of detection technologies. First, there are ionization detectors. These use a small bit of safely shielded radioactive material that electrically charges, or ionizes, the air molecules between two metal plates. This produces a small electric current flowing from one plate to the other in the air.

How do relays work?

Differential protection relays: These trigger when there are current or voltage imbalances in two different parts of a circuit. Frequency protection relays (sometimes called underfrequency and overfrequency relays): These solid-state devices trigger when the frequency of an alternating current is too high, too low, or both.

Why do car starter motors draw so much current?

All electric motors consume more current at startup compared to steady state. Check out the label on your fridge for example (or look at this one): the max current on the label is 2-3 times higher than the value you''d obtain from power to voltage ratio.. The reason behind this lies in the properties of electric motors.

Current flow in batteries?

$begingroup$ Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.
