Measuring resistance
For these activities:
- use Challenge to see how much you already know
- use Reinforcement for extra practice.
Insulation testing
To protect against the dangers of eletrocution, electrical conductors are insulated. Measuring the resistance of this insulation to ensure safety is an important task and it requires the use of a specialised meter.
These activities present information, questions and practical experience using an insulation resistance (IR) meter.
