- Q1. What is the difference between voltage and current.
- Ans.
Voltage is the potential difference between two points in a circuit, while current is the flow of electric charge through a conductor.
Voltage is measured in volts, while current is measured in amperes.
Voltage is the driving force that pushes the current through a circuit.
Current is the rate of flow of electric charge, while voltage is the energy per unit charge.
In a simple analogy, voltage is like the pressure in a wat...
- Q2. What is the difference between primary and secondary winding of transformers
- Ans.
Primary winding receives electrical energy while secondary winding delivers the transformed energy in transformers.
Primary winding is connected to the input voltage source
Secondary winding is connected to the output load
Primary winding has fewer turns compared to secondary winding
Primary winding has thicker wire compared to secondary winding
Primary winding is usually located closer to the core of the transformer
