My understanding is that it takes about 20,000 volts to arc between the two parts of the spark plug and most automotive coil put out 20,000-50,000 volts.
Your first touch of live primary Tesla coil voltage (10000 volts) has a good chance of being fatal and will easily stop your heart. The coil dicharge goes up to one and a half millions volts.
I believe is 12 to 14 volts.
For a 1973 Thunderbird with a 7.5-liter engine, the ignition coil typically receives around 12 volts from the battery when the engine is running. However, when measuring the voltage at the coil, it's important to consider that the voltage may vary slightly depending on the condition of the electrical system and any added resistance. Ideally, ensure the coil receives sufficient voltage to function properly, typically around 9 to 12 volts, to maintain optimal spark performance.
neither...it should have 14.63 volts
Fully charged battery should have 12.6 volts. 75% charged 12.4 volts, 50% charged 12.2 volts, & 25% charged 12.0 volts.
12 volts DC.
Should be 9 larger wires (1 to each spark plug and 1 to the coil) Should also be a connector (small wire that leads to the negative side of the coil)
An ignition coil typically generates a high voltage of around 12,000 to 45,000 volts, depending on the vehicle and the specific coil design. The primary side of the ignition coil operates at a low voltage, usually around 12 volts from the battery, while the secondary side produces the high voltage needed to create a spark at the spark plug. This high voltage is essential for igniting the air-fuel mixture in the engine's combustion chamber.
From 13.5 to 15.5 Volts.
13.5 to 15.5 volts
Just 12, it is the same as every other system in the vehicle
Voltage is a measure of "pressure" in an electrical circuit. Electrical voltage is produced as a function of the number of windings in a field coil in comparison to the number of windings in the stator of a generator. the greater difference in the number of windings the greater the voltage. This voltage can also be modified by transformers, which are coils in the circuit that transfer electricity from one coil to another by induction. The difference in the number of windings in one coil to the other coil will determine the change in voltage. So by taking a circuit with a voltage of , say, 110 volts, by installing a transformer that has twice as many windings in one coil than the other, you can transform the voltage from 110 volts to 220 volts.
