When a charging current is applied to a nickel-cadmium battery, the cells emit gas

Toward the end of the charging cycle.

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

Prevent sediment buildup from contacting the plates and causing a short circuit.

A thermal switch, or thermal protector, as used in an electric motor, is designed to

Open the circuit in order to allow cooling of the motor.

Typical application for zener diodes is as

Voltage regulators

Electrostatic fields are also known as

Dielectric fields

In a parallel circuit with four 6-ohm resistors across a 24-volt battery, what is the total voltage across resistor-three (VR3) in the circuit?

24 volts

Which statement regarding the hydrometer reading of a lead-acid storage battery electrolyte is true?

The hydrometer reading does not require a temperature correction if the electrolyte temperature is 80° F.

How many amperes will a 28-volt generator be required to supply to a circuit containing five lamps in parallel, three of which have a resistance of 6 ohms each and two of which have a resistance of 5 ohms each?

25.23 amperes

A 24-volt source is required to furnish 48 watts to a parallel circuit consisting of four resistors of equal value. What is the voltage drop across each resistor?

24 volts

What will a voltmeter read if properly connected across a closed switch in a circuit with electrical power on?

Zero voltage.

A fully charged lead-acid battery will not freeze until extremely low temperatures are reached because

Most of the acid is in the solution.
