An electrician’s job requires the constant calculation of voltages, measurements, and more. To do this, they will use basic arithmetic and fractions. For example, when bending conduits, they need to know the correct angle and distance between the bending points. Every job in the electrician industry uses math. A good foundation in math will help an electrician understand the National Electrical Code (NEC).

Trigonometric calculations

Electrical engineers need to understand trigonometric calculations to design power circuits. Electrical circuits are complicated systems that can fail if they are not appropriately prepared. Because of this, electricians should be familiar with the concepts and use them as part of their day-to-day tasks. For example, electricians use trigonometric calculations to solve missing values in circuits with alternating currents.

What Type of Math Do Electricians Use?

An electrician is constantly calculating measurements and voltages. They will also use fractions and basic arithmetic to determine the critical distance and angle.

For example, when they bend conduits, they must know basic right-angle trigonometry to determine the correct angle and distance between two bending points. This type of calculation is used in almost every job. Moreover, an electrician needs to know the NEC (National Electrical Code) to understand its requirements.

Many construction workers use trigonometry to design structures and fittings. This helps them meet building code requirements. For example, an electrician might use plane trigonometry to design a roof structure. Using this method, they can determine the height of a structure by considering the angle from an observer.

Analytic geometry

Analytic geometry is an essential topic for any electrical engineer. This type of geometry teaches students how to solve problems related to shapes and measurements, and it is also a prerequisite for advanced study in electrical engineering. Analytic geometry also has a history dating back to the ancient Greeks and is a fundamental field subject.

The definition of an analytic triangle includes the properties of the angles it crosses. It is also used to solve equations. For example, the formula x cos A + y sin A rotates the graph by angle A. Another standard transformation is skewing. For example, an electrician might use an x-cos -y-sin -x-cos function to calculate the slope of a line.

Electricians use analytic geometry to calculate the lengths and angles of electrical wires. This mathematics helps them solve complex problems. It also helps them understand the relationship between points and straight lines.


Electricians often have to work with calculations. Many of these calculations require calculus. For example, an electrician can use integration to find the length of a cable hung or buried. This is essential information for power companies planning to install hundreds of miles of the new line. The application of calculus is vast and varied.

Engineers and statisticians also use calculus. These people use it to calculate rates of change or weight. They can also use it to find the center of mass of an object, such as an object in space. Additionally, they can use calculus to figure out how many things can fit into a box.

Many electricians also use algebra, trigonometry, and calculus. Whether bending pipes or calculating electrical calculations, math is a vital part of the profession.
