Answer
The seven common electrical tests performed for safety and troubleshooting are:
- Continuity Test - checks if current can flow through a circuit
- Voltage Test - measures electrical potential difference
- Current Test - measures the flow of electric charge
- Resistance Test - measures opposition to current flow
- Insulation Resistance Test - checks for insulation breakdown
- Earth/Ground Test - verifies proper grounding for safety
- Polarity Test - ensures correct positive/negative connections
These tests help electricians diagnose problems, verify proper installation, ensure safety compliance, and prevent electrical hazards.
