Question

One kilowatt is equal to _____ horse power.
E. $1.34$
F. $1.32$
G. $1.28$
H. $1.38$

Answer 1

Hint: Measurement of energy is done in Kilowatt hour. It can also be written as${\rm{kWh}}$.
The measurement of power is horsepower and it can be written as${\rm{hp}}$.
Power is defined as the energy required to do work and the capacity of doing work is called
energy. The SI unit of energy is joule and the SI unit of power is watt. Basically power is related
to energy. It is the energy per unit of time.
One kilowatt is equal to 1.34 horsepower.
Horsepower and kilowatt are two different units but their physical value is the same or identical.
They are equal to their proportional part when divided or multiplied. One kilowatt is equal to
$1000$ watts. A kilowatt hour or ${\rm{kWh}}$ means $1000$ watt. Horse power is that unit
which is used to measure the efficiency of engines of vehicles and other machineries as well as
motor parts. It is a mathematical approach to evaluate the power of engines and motors. The term
horsepower was invented by James Watt who was the prime inventor of steam engines.
Kilowatt is the unit that is used to measure electricity. When a device is more powerful the number of watt also increases.
A familiar term brake horsepower or bhp is defined as the force that is used to halt an engine.

Note: Difference between horsepower and brake horse power is that hp does not take the
frictional loss into account whereas bhp includes this to account.
