- Q3. Balence an organic reaction .
- Ans.
Balancing an organic reaction involves adjusting coefficients to ensure the same number of atoms of each element are present on both sides of the equation.
Identify the reactants and products
Count the number of atoms of each element on both sides
Adjust coefficients to balance the equation
Check that the equation is balanced
Example: C2H5OH + O2 -> CO2 + H2O
Example: 2C2H5OH + 3O2 -> 4CO2 + 6H2O

- Q1. WHAT IS DROPOUT SWITCH
- Ans.
A dropout switch is an electrical switch that opens when the voltage drops below a certain level.
It is used to protect electrical equipment from damage due to low voltage.
It can be manually or automatically reset.
Examples include low voltage disconnect switches and thermal overload switches.
It is commonly used in battery systems to prevent over-discharge.
It is also used in power distribution systems to prevent damage t
- Q2. WHAT IS THE DIOD
- Ans.
A diode is an electronic component that allows current to flow in only one direction.
It has two terminals, an anode and a cathode.
It is commonly used in rectifiers to convert AC to DC.
It can also be used as a voltage regulator or a signal modulator.
It is made of semiconductor materials such as silicon or germanium.
It has a forward voltage drop that varies depending on the material and temperature.
- Q3. WHAT IS THE HRC FUSE
- Ans.
HRC fuse stands for High Rupturing Capacity fuse. It is a type of fuse that can withstand high fault currents.
HRC fuse is designed to protect electrical equipment from overcurrents.
It has a high breaking capacity and can interrupt high fault currents without causing damage to the equipment.
HRC fuse is commonly used in industrial and commercial applications.
It is available in different sizes and ratings to suit differen...
- Q4. WHAT IS THE 4 POLE MOTER RPM..
- Ans.
The RPM of a 4 pole motor is determined by the frequency of the power supply and the number of poles.
The RPM of a 4 pole motor is directly proportional to the frequency of the power supply.
The RPM of a 4 pole motor is inversely proportional to the number of poles.
For example, a 4 pole motor connected to a 60 Hz power supply will have an RPM of approximately 1800.
If the power supply frequency is increased to 120 Hz, the...
- Q5. CAN U CONVERT 10KW MOTER INTO HP
- Ans.
Yes, 10 kW is equal to 13.41 HP.
1 kW = 1.34 HP
Therefore, 10 kW = 10 x 1.34 = 13.41 HP
Conversion formula: HP = kW x 1.34
- Q6. WHAT IS ISOLATER
- Ans.
An isolator is an electrical switch that isolates a part of the circuit from the rest for maintenance or safety purposes.
Isolators are used to disconnect a circuit from the power source.
They are often used in high voltage applications.
Isolators are different from circuit breakers or fuses, as they do not provide protection against overloads or short circuits.
They are commonly used in industrial settings and power distr...
- Q7. WHAT IS THE DC VOLTAGE AND AC VOLTAGE
- Ans.
DC voltage is a constant voltage while AC voltage changes direction periodically.
DC voltage is a steady voltage that flows in one direction only
AC voltage changes direction periodically and has a frequency measured in Hertz
DC voltage is commonly used in batteries and electronic devices
AC voltage is used in household power outlets and electrical grids
- Q8. WHACH MOTER CAN CONTROL SPEAD
- Ans.
A motor's speed can be controlled by a variable frequency drive (VFD).
A VFD can adjust the frequency of the electrical power supplied to the motor, which in turn controls its speed.
VFDs are commonly used in industrial settings to control the speed of motors powering machinery.
VFDs can also improve energy efficiency by reducing the amount of power consumed by the motor.
Other methods of controlling motor speed include us...
