The number of electrical degrees between the time an AC voltage passes through zero, going in a positive direction, and the time the current passes through zero going in the same direction. If it were possible for a circuit to be purely inductive, having neither capacitance nor resistance, the voltage would lead the current by 90°. This circuit would have a phase angle of 90°.

The number of lines of magnetic flux per unit of area. Magnetic flux density is measured in gausses. One gauss is equal to one line of flux (one maxwell) per square centimeter.

The number of protons in the nucleus of an atom of the element. The atomic number of an element determines the position of the element in the periodic table of elements.

The number of revolutions per minute an aircraft engine can produce when the aircraft is not moving. The static RPM is lower than the RPM the engine develops in flight because of the increased power made possible by forward movement ramming air into the carburetor inlet.

The number of times a number is multiplied by itself. The power is indicated by an exponent, a small superscript number such as the 3 in 43. For example, 43 = 64. This is the same as 4 . 4 .4 = 64.

The number system whose base is two. It uses only two values, zero and one. Each position represents a value twice that of the position to its right. For example:
: 643216 8 4 2 1
: 0 0 0 0 0 0 1 = 1
: 0 0 0 0 0 1 0 = 2
: 0 0 0 0 1 0 0 = 4
: 0 0 0 1 0 0 0 = 8
: 0 0 1 0 0 0 0 = 16
: 0 1 0 0 0 0 0 = 32
: 1 0 0 0 0 0 0 = 64
The binary number system is useful when working with digital electronics, because the two basic conditions of electricity, on and off, can be used to represent the two bits of the binary number system. When the system is on, the bit one is represented, and when it is off, zero is represented.

The number, in a series, that has as many numbers below it as there are above it. In the series of numbers 1, 2, 3, 4, 5, 6, 7 the median is 4. There are three numbers below 4 and three numbers above it.
