These books provide a complete set of course notes, leaving the students free to spend their time learning and doing. Together they cover the BTEC module Electrical and Electronic Principles N, which forms a foundation in electricity for many HNC/D engineering students. In approach they assume a minimum of background knowledge, starting with an explanation of such fundamentals as SI units, scientific notation, graphs and report writing. Some topics get a slightly broader treatment than is needed for BTEC, making the set an ideal grounding in electricity for other FE students, such as those on relevant CGLI and NVQ schemes.
