Electrical Basics for Beginners

From “what is a volt?” to holding a multimeter, wiring a lamp and a socket, and finding the fault yourself.

The lessons are in Arabic for now; the English version is on the way. Device screens and codes are the same as on the real hardware.

The multimeter lesson in the basics course: an interactive multimeter with a rotary switch, measuring a socket
From the multimeter lesson: turn the dial, place the probes and read the value.

Electrical basics

What you'll learn

  • Voltage, current, resistance and power, with simple analogies
  • Series vs parallel, and why a house is wired in parallel
  • Work out energy use and the electricity bill in kWh
  • AC vs DC, single phase vs three phase, and wire colours
  • Use a multimeter safely: volts, ohms, continuity and current
  • Test a heater, motor, fuse and transformer, good or bad
  • Choose the right cable size and breaker for a load
  • Wire a switched lamp, an earthed socket and a two-way switch

The lessons

In order. Every lesson has a short explanation, hands-on experiments and questions.

  1. What is electricity?Free
    Voltage, current, resistance and power with the water analogy, and how the bill is calculated
  2. Voltage and currentFree
    Volts push, amps flow: the closed circuit, current direction, units and how to measure them
  3. Conductors and insulators
    Copper, aluminium, plastic and water: what conducts, and how wire length and thickness matter
  4. Series and parallel
    Lamps in a row and side by side, current and voltage in each, why homes use parallel, and batteries
  5. Power and energy
    Watts, kilowatts and horsepower, kWh and the home bill, heat in the wire, and efficiency
  6. Types of electricity
    DC and AC, single phase and three phase, wire colours and earthing
  7. Safety and toolsFree
    The voltage tester screwdriver, the RCD and the tools you should carry
  8. The multimeter
    Measure volts, ohms, continuity and current without getting hurt or blowing the meter
  9. Measuring appliances
    Heater, kettle, lamp, fuse and motor, and current with a clamp meter
  10. Transformers and power supplies
    How a transformer steps voltage down, how a power supply turns AC into DC, and how to test them
  11. Ohm's law, cables and breakers
    Work out current from power, and choose the breaker and cable size correctly
  12. Wiring a lamp and socket
    Wire it yourself: a switched lamp, an earthed socket, a two-way switch, two lamps in parallel
  13. Common home faults
    A game where you find the fault with a tester and multimeter, plus the final exam
Who it's for

Who this course is for

  • You're completely new to electricity and don't know where to start
  • Technical school and first-year engineering students
  • You want to fix things at home yourself, safely
  • Before you take the classic control or instrumentation course
FAQ

Before you ask

Do I need to know anything first?
Nothing at all. The course starts from zero and explains every word with everyday analogies before any numbers.
Do I need a multimeter or tools?
No. The multimeter, boards and devices are all interactive in the page. If you have a real multimeter, you can repeat the same steps on it afterwards.
Is there a certificate?
Yes. When you finish every lesson and the final exam while signed in, you can get a Course Completion Certificate with a verification code and QR code. It confirms you completed the course; it is not an accredited qualification.
Is the course free?
The first two lessons and lesson 7 are open to everyone, no account needed. The other lessons need a free account you can create in seconds with your email.
Can I study on my phone?
Yes. The course works on phones, tablets and computers, and your progress is saved to your account so it follows you to any device.
