Basic DC Circuitry

Introduction

Delegates attending this course will be introduced to Ohm’s Law and the use of a Digital Multimeter to measure Voltage, Current and Resistance.

Objectives

On successful completion of the course the candidate will be able to:

Use a Multimeter to measure DC Voltages, Currents and Resistance.

State the relationship between the Voltage and Current flowing in a circuit with respect to its resistance, as per Ohm’s Law

Using Ohm’s Law, calculate the expected Voltage, Current or Circuit Resistance when two of the three components are known.

Identify a resistors value from its colour coding.

Calculate the resistance of resistors connected in Series and Parallel.

Understand the operation of a variable resistor.

Who Should Attend

Network Rail S&T Technicians and those who work within maintenance/installation teams who will be expected to use a Digital Multimeter to measure circuit voltages, currents or resistance?

Features

Candidates will construct simple circuits during the course, from which they will be able to measure actual circuit voltages, currents and resistances using a Digital Multimeter. They will then be expected to compare these reading to expected results calculated by using Ohm’s Law.

Learning Approach

Classroom theory sessions using visual aids, practical demonstrations and practice training aids.
