- Q1. Different between ac and dc
- Ans.
AC stands for alternating current, which changes direction periodically. DC stands for direct current, which flows in one direction constantly.
AC changes direction periodically, while DC flows in one direction constantly
AC is used in household appliances and power distribution, while DC is used in batteries and electronic devices
AC can be easily converted to different voltages using transformers, while DC requires more
- Q2. Electrical machine
- Q3. Different between machine and generator
- Ans.
A machine is a device that uses energy to perform a task, while a generator is a specific type of machine that converts mechanical energy into electrical energy.
Machines can perform a variety of tasks using different forms of energy, such as mechanical, electrical, or thermal.
Generators specifically convert mechanical energy, usually from a rotating shaft, into electrical energy.
Examples of machines include motors, pum...
- Q4. Different between network and circuit
- Ans.

- Q1. Explain the solar energy
- Ans.
Solar energy is the energy derived from the sun's radiation, which can be converted into electricity or used for heating purposes.
Solar energy is renewable and sustainable, making it an environmentally friendly energy source.
Solar panels are used to capture sunlight and convert it into electricity through the photovoltaic effect.
Solar energy can be used for various applications such as powering homes, businesses, and e...
- Q2. Explain the solar power plant
- Ans.
A solar power plant is a facility that converts sunlight into electricity using photovoltaic panels or mirrors to concentrate solar energy.
Solar panels or mirrors capture sunlight and convert it into electricity through the photovoltaic effect
The electricity generated can be used to power homes, businesses, or even entire cities
Solar power plants can be either photovoltaic (PV) or concentrated solar power (CSP) systems
...
- Q3. Explain the solar energy translation and distribution
- Ans.
Solar energy is converted into electricity through photovoltaic cells and then distributed through a grid system.
Solar energy is captured by solar panels, which contain photovoltaic cells that convert sunlight into electricity.
The electricity generated is then fed into an inverter, which converts it from direct current (DC) to alternating current (AC) for use in homes and businesses.
The AC electricity is then distribut...
- Q4. Explain the solar power plant maintenance
- Ans.
Solar power plant maintenance involves regular cleaning of panels, inspection of components, and monitoring of performance.
Regularly clean solar panels to remove dirt and debris that can reduce efficiency
Inspect components such as inverters, wiring, and batteries for any signs of wear or damage
Monitor performance metrics like energy output and system efficiency to identify any issues early

Asynchronous motors
Squirrel cage motors
- Q3. What is exciter
- Ans.
An exciter is a device that supplies the field current to the rotor winding of a synchronous machine.
Supplies field current to the rotor winding
Helps in generating the magnetic field in the rotor
Essential component in synchronous machines
Can be either brushless or brush type
Examples include static exciter and rotating exciter

- Q1. Why we cannot operate transformer in dc supply
- Ans.
Transformers cannot operate on DC supply due to the absence of changing magnetic field required for induction.
Transformers work on the principle of electromagnetic induction, which requires a changing magnetic field.
DC supply produces a constant magnetic field, which does not induce a voltage in the secondary coil of the transformer.
AC supply, on the other hand, produces a changing magnetic field, allowing for inductio...

- Q1. Why we cannot measured transformer in kw
- Ans.
Transformers cannot be measured in kW because they do not consume power, they only transfer it.
Transformers do not have any moving parts or internal power losses, so they do not consume power themselves
The power rating of a transformer is given in kVA (kilovolt-amperes) which represents the maximum amount of power it can transfer
The power factor of the load connected to the transformer determines the actual power in kW
