BTEC Level 3 Unit 6 - Electrical and Electronic Principles

Unit Information

This is a mandatory unit

Credit value: 10

This unit aims to give learners an understanding of the underlying physical principles on which electrical and electronic devices and circuits depend.

The BTEC specification for this unit can be found here.

On completion of this unit a learner should:

  1. Be able to use circuit theory to determine voltage, current and resistance in direct current (DC) circuits
  2. Understand the concepts of capacitance and determine capacitance values in DC circuits
  3. Know the principles and properties of magnetism
  4. Be able to use single-phase alternating current (AC) theory.


This unit has 6 Assignments:

  1. Assignment 6 - Diodes and Power Supplies (P3)

Note: Assignment 6 is set in Unit 35 - Principles and Applications of Electronic Devices and Circuits.

Assignment Tracking submission and progression sheets can be viewed by asking the unit tutor
