Accepted Answer

The maximum sustained potential difference a component can withstand between its terminals without risk of insulation breakdown, performance degradation, or permanent damage. This absolute maximum rating, specified in volts (V) for either DC or AC (RMS) c

Question 20

What is the Current Rating (Amps)

Accepted Answer

Specifies the maximum continuous current a conductor, connector, or component can safely carry without exceeding its thermal limits, thereby preventing overheating and ensuring long-term reliability. This ampere (A) rating is a fundamental parameter for s

Question 21

What is the Ingress Protection

Accepted Answer

A standardized rating system (IEC 60529) that classifies the degree of protection provided by an enclosure against the intrusion of solid objects (first digit) and liquids (second digit). It quantifies resistance to dust, accidental contact, and water ing
