The least count of a Vernier caliper is the smallest measurement that can be accurately read.

• The least count is determined by the number of divisions on the main scale and the Vernier scale.

• It is calculated by dividing the smallest division on the main scale by the total number of divisions on the Vernier scale.

• For example, if the smallest division on the main scale is 0.1 mm and the Vernier scale has 10 divisions, the least count would be 0.01 mm.

• The least count represents t...read more

A motor is a device that converts electrical energy into mechanical energy, while a transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Motor converts electrical energy into mechanical energy

• Transformer transfers electrical energy between circuits through electromagnetic induction

• Motors are used in appliances like fans, washing machines, and cars

• Transformers are used in power distribution systems to step up o...read more

Power factor is a measure of how effectively electrical power is being used in a circuit.

• Power factor is the ratio of real power to apparent power in a circuit.

• It is a number between 0 and 1, with 1 representing perfect efficiency.

• A low power factor indicates inefficient use of electrical power.

• Power factor can be improved by using power factor correction devices.

• For example, inductive loads like motors have a lower power factor compared to resistive loads.

Options strategies like strangle and ratio involve buying or selling multiple options to profit from market movements.

• Strangle involves buying both a call and put option with different strike prices but the same expiration date.

• Ratio involves buying or selling a different number of options to create a specific risk/reward profile.

• Both strategies can be used to profit from volatility in the underlying asset.

• Strangle can be used when expecting a significant price movement but u...read more

Pump, compressor, and engine are all mechanical devices used to transfer energy.

• A pump is used to move fluids, such as water or oil, from one place to another.

• Types of pumps include centrifugal, positive displacement, and axial flow.

• A compressor is used to increase the pressure of a gas, such as air or natural gas.

• Types of compressors include reciprocating, rotary screw, and centrifugal.

• An engine is a machine that converts fuel into mechanical energy to power other machines.

• T...read more
