Course description

In Direct Current Fundamentals for Non-Electrical Engineers, you'll learn ...

  • How to find voltage, current and resistance in series and parallel circuits
  • Why conventional flow notation is easier for non-electrical engineers to understand
  • How to analyze a circuit using the principles of Kirchhoff’s Laws
  • How bridge circuits are used for component measurement and sensor signal conditioning

Direct current (DC) is a continuous electric current that flows in one direction only, without substantial variation in magnitude. DC is commonly found in many extra-low voltage applications and some low-voltage applications, especially where these are powered by batteries or solar power systems, which can produce only DC. Most electronic circuits require a DC power supply.

Direct current is not used for long-distance power transmission because it is difficult to step up the voltage to a level that is efficient for energy transfer and then to step the voltage back down again for safe domestic use. It is possible with alternating current (AC) to build electric generators, motors and power distribution systems that are far more efficient than DC, and so we find AC used predominately across the world in high power applications.

In this course, you’ll learn about the concepts of voltage, current, resistance, capacitance and inductance and you’ll learn how to analyze both series and parallel DC circuits. The course uses pictorial representations and fluid flow analogies to help non-electrical engineers understand the material.

This is an excellent refresher course for mechanical, civil, process, control systems, HVAC, industrial and transportation engineers.
