When we need
to turn on electronic equipment with a large initial power such as television,
water pump motor and so on, but the power rating we have is small, then the MCB
will soon break out our electricity current.
As a solution, then we can use current limiting circuit start, until the steady
state. When steady conditions have achieved the work of this current limiting
circuit we switch off.

Note: The used relay is 12 volt 5 ampere. NC directly
connected to the load, whereas NO is connected to resistor 1 K
