Exam 12: Electric Current and Related Variables in Engineering

Electric current is a fundamental dimension.

In all batteries, electricity is produced by

In general, there are two ways in which the sun's energy is converted into electricity:

Every engineer needs to understand the fundamentals of electricity and magnetism.

The distribution of light on a horizontal surface is known as

The SI unit for electric current is

In lighting design, a variable called CRI is often used.What does CRI stand for?

Electrical components that store energy on two oppositely charged electrodes, rather than through a chemical reaction are known as

The law that states that at any given time, the sum of the currents entering a node must equal the sum of the currents leaving the node is know as

In certain circuits, if one of the elements fails, that failure prevents the current from flowing through other elements in the circuit; thus the entire circuit fails.This type of circuit is a

The basic law of electric charges states that unlike charges attract each other while like charges repel.

In SI units, the unit of charge is the coulomb (C).

Primary cells are batteries that can be recharged while secondary cells are batteries that cannot be recharged.

A numbering system that describes the size of an electric conductor is AWG.What does AWG stand for?

The amount of work required to move charge between two points is represented by

Capacitors are used for

The ratio of how much light is produced by a lamp (in lumens) to how much energy is consumed by the lamp (in watts) is known as

The ratio of the diameter of No.1 AWG wire to No.2 is

How many kW-hour is consumed by a TV set that uses 250 watts when it is left on for 4 hours?

When it comes to wire size, the larger the gage number the larger the wire diameter.
