Electrical equipment — general information

The battery, generator and starter provide engine start, each of them performs its function and is connected with the others. So, without a battery, you cannot turn on the starter; without a starter, the engine and generator will not start to work. The battery cannot be recharged without a generator.

For the passage of electric current requires a closed circuit. It consists of source (e.g. battery), consumers (lamps, starter) and wires that connect the current source and consumers.

Voltage is a potential difference, measured in volts (IN).

The current strength characterizes the amount of electric charge transferred through the cross section of the conductor per unit time, measured in amperes (A).

Power - the product of voltage and current strength, which shows what kind of electrical work the current source performs in relation to the consumer, measured in watts (Tue).

Resistance provided by an electrical circuit (conductor) electric charges moving in it. This is the ratio of the voltage applied to the resistance to the strength of the current flowing through the resistance, the unit is Ohm.

The wire. Wire thickness (cross-sectional area) depends on the consumer. A 0.5 mm² section is sufficient for the pilot lamp, a 16 mm² wire section is required for the starter. A wire that is too thin can overheat, resulting in a voltage drop. In this case, for example, not 12 V, but 10 or even 9.5 V reaches the headlights. As a result, the headlights become dim.
