Front

What is the purpose of providing a space underneath the plates in a lead acid battery's cell container?

Back

To prevent sediment build up from contacting the plates and causing a short circuit.

Front

When will the output of a logic gate be 0?

Back

When one or more inputs are 0.

Front

Why do nickel cadmium batteries show a lower liquid level during discharge?

Back

Because the electrolyte becomes absorbed into the plates.

Front

What is the voltage across an 8 ohm resistor if the total voltage is 24 volts?

Back

24 volts.

Front

What unit is used to express electrical power?

Back

Watt.

Front

What is the function of a lead acid battery?

Back

To store and provide electrical energy through chemical reactions.

Front

Define 'electrolyte' in the context of batteries.

Back

A substance that conducts electricity through the movement of ions, typically a liquid or gel.

Front

What is the principle of operation of a logic gate?

Back

To perform a logical operation on one or more binary inputs to produce a single binary output.

Front

Explain the term 'short circuit' in electrical systems.

Back

An unintended path of low resistance that allows current to flow, potentially causing damage.

Front

What happens to the electrolyte in a battery during charging?

Back

The electrolyte undergoes a chemical reaction that restores the active materials on the plates.
