Online maths course for students and electricians. All the maths you need as an electrician in the workplace or for your study in the classroom.

Study on any internet connected device.

Full of clear equations and calculations supported by examples and hundreds of practice questions.

The course does not require you to have a background in mathematics, it covers topics from first principles to complex three-phase circuits. At each step of the way the topics explain clearly how to understand the components of the equations and how to combine them into solutions.

The course is divided into lessons with separate topics covering equations and concepts in details. Every lesson is accompanied by practice questions designed to give students and electricians the confidence to apply the maths learned. This course will take you from Zero to all the maths you need for Level 3 electrical qualifications.

The course has been designed specifically to assist students taking City & Guilds exams including: 2382 (18th Edition Wiring Regulations), 2391-50, 51 and 52 (Inspection and Testing) and 2365 (Electrical Installations Technology).

We have published a significant update on the Maths for Electricians course.
All of the feedback fields have been updated to provide important context to help you understand the concept which the question is testing.

By example:

Question statement
A device on a 400 V circuit with a power factor of 0.99 has a load of 14.3 kW, What is the current flow?
Answer options
32.5 A
35.39 A
54.17 A
36.11 A
Current Feedback
I = W/(V x Pf)

New Feedback
To calculate the current flow in a circuit with a power factor of 0.99 and a load of 14.3 kW on a 400 V circuit, you can use the formula: Current (A) = Power (W) / (Voltage (V) * Power Factor). Plugging in the values: Current = 14300 W / (400 V * 0.99) = 36.11 A.

We have removed the simple short form feedback and replaced it with long form feedback in the style indicated. Every question in the course has been updated. You can see the new material on the Demo page.


Course remains available to students for 12 months from date of purchase.
