10+ Mehala Machines Interview Questions and Answers

1 horsepower is equivalent to 0.7457 kilowatt-hours (kWh).

• 1 horsepower is equal to 0.7457 kilowatts.

• To convert horsepower to kilowatt-hours, you need to multiply by 0.7457.

• For example, if a machine has a power rating of 100 horsepower, it would be equivalent to 74.57 kilowatt-hours.

The unit of resistance is ohm (Ω).

• Resistance is the opposition to the flow of electric current.

• Ohm is named after Georg Simon Ohm, a German physicist.

• The symbol for ohm is the Greek letter omega (Ω).

The formula for speed is distance divided by time.

• Speed = Distance / Time

• Units of speed can be meters per second, miles per hour, or kilometers per hour.

• Speed can be calculated for any type of motion, including walking, running, or driving.

• Speed can also be used to calculate the velocity of an object, which takes into account its direction of motion.

The unit of magnetic flux is the Weber (Wb).

• The unit of magnetic flux is a measure of the total magnetic field passing through a given area.

• It is represented by the symbol Wb.

• One Weber is equal to one Tesla multiplied by one square meter.

• The magnetic flux can be calculated by multiplying the magnetic field strength by the area it passes through.

The unit of resistance is ohm.

• The unit of resistance is measured in ohms (symbol: Ω).

• Resistance is a measure of how much a material or component opposes the flow of electric current.

• For example, a standard resistor may have a resistance of 100 ohms.

The unit of speed is meters per second (m/s) or kilometers per hour (km/h).

• Speed is the measure of how fast an object is moving.

• The SI unit of speed is meters per second (m/s).

• Another commonly used unit of speed is kilometers per hour (km/h).

• Other units of speed include miles per hour (mph) and feet per second (ft/s).

The unit of electric charge is the coulomb (C).

• The unit of electric charge is a fundamental quantity in physics.

• It is denoted by the symbol 'Q'.

• One coulomb is equal to the charge of approximately 6.242 × 10^18 electrons.

• Electric charge is measured using an instrument called an electrometer.

The unit of length is a measurement used to determine the distance between two points.

• Common units of length include meters, feet, and inches.

• Length can also be measured in kilometers, miles, or centimeters.

• The unit of length is important in fields such as construction, engineering, and physics.

The formula for resistance is R = V/I, where R is resistance, V is voltage, and I is current.

• Resistance is the measure of how much a material opposes the flow of electric current.

• The unit of resistance is ohm (Ω).

• Resistance can be calculated using the formula R = V/I.

• For example, if the voltage is 12 volts and the current is 2 amps, the resistance would be 6 ohms.
