Batteries
What type of water should be used to maintain the correct water level in gel and AGM batteries?
Distilled water should be used to maintain the correct water level in gel and AGM batteries.
What is the function of a relay in an electrical circuit?
A relay uses low amps to control high amps, while an ignition coil uses low voltage to control high voltage.
What is the total voltage of a 12-volt car battery made up of six 2.1-volt cells in series?
12.6V
What are the functions of terminals 30, 85, 86, 87, and 87a in a relay?
Terminals 85 and 86 are on the coil side and can be placed interchangeably, terminal 30 is the input, and terminals 87 and 87a are outputs with specific functions depending on the relay's use.
What happens to the voltage and current when batteries are added in series and parallel circuits?
In a series circuit, the voltage increases with more batteries, while in a parallel circuit, the voltage remains the same but the current increases.
What is the function of a fusible link in a circuit?
A fusible link is a wire designed to burn out and separate when the current exceeds a certain level, thereby protecting the circuit.
What tools are commonly used to test car batteries?
Hydrometers and refractometers are commonly used to test car batteries.
Does the placement of a switch on the power side versus the ground side affect the functionality of an electrical circuit?
No, the placement of a switch on the power side versus the ground side does not affect the functionality of an electrical circuit.
How does a car battery generate and store electricity?
A car battery uses reversible chemical reactions within its six cells to produce a total of 12 volts, which is sufficient to start the car engine and power various electrical components.
What voltage reading will you get in a complete circuit before the voltage is used up?
In a complete circuit, the voltage reading will be 12 volts until it is used up.
