Difference Between Ohmic and Non-Ohmic Conductors
💡 Key learnings: Ohmic Conductors: Obey Ohm’s Law; current is directly proportional to voltage. Resistance remains nearly constant under normal conditions. Non-Ohmic Conductors: Do not
Why Transformers Are Rated in kVA, Not in kW
Transformers are always rated in kVA (kilovolt-amperes) rather than kW (kilowatts) because their design is based on voltage and current capacity, not the power factor
Why Motor Rated in KW instead of KVA?
A motor is rated in kilowatts (kW) because its primary purpose is to produce useful mechanical output power to drive a load. Kilowatts represent the
Difference Between kVA and kW – Explained With Formulas & Examples
💡 Key Learnings: kW (Active Power): kW measures the real power consumed by electrical equipment to perform actual work. kVA (Apparent Power): kVA represents the
