- Q1. Power rating of cable
- Ans.
Power rating of a cable indicates its maximum load capacity, ensuring safe and efficient electrical transmission.
Power rating is typically expressed in watts (W) or kilowatts (kW).
It depends on factors like cable material, cross-sectional area, and insulation type.
For example, a 2.5 mm² copper cable can safely carry around 20-25 amps.
Ambient temperature and installation conditions also affect the power rating.
Cables ar...

(2 Questions)
- Q1. What is voltage
- Ans.
Voltage is the electric potential difference between two points, driving current flow in a circuit.
Voltage is measured in volts (V).
It represents the energy per unit charge available to move electrons.
Example: A standard AA battery has a voltage of 1.5V.
Higher voltage can lead to greater current flow, given a constant resistance (Ohm's Law).
Voltage can be AC (alternating current) or DC (direct current).
- Q2. Current rating of transformer
- Ans.
The current rating of a transformer indicates the maximum current it can handle safely without overheating.
Current rating is determined by the transformer's design and cooling method.
Example: A 100 kVA transformer at 400V has a current rating of approximately 144A.
Higher current ratings require larger conductors and better cooling systems.
Transformers are rated for primary and secondary currents, which can differ signi
