Question

Starter is used in
A. High power electric motors
B. Low power electric motors
C. Transformers
D. Galvanometer

Answer 1

To initiate engine operation a device is used to rotate the internal combustion engine. There are static starters, hydraulic starters, and pneumatic starters. Internal combustion engines depend on the inertia of each cycle to initiate the next cycle.to start the combustion engine the first cycle must be given power from the other source.

Complete step by step solution:
Starters are used in large engines to initial internal combustion engines. The electric starter motor is a common type of starter used in diesel engines, which is a permanent magnet with a starter solenoid mounted on the starter.
When DC is supplied to this mounted solenoid by the ignition switch, the solenoid produces a magnetic field that entangles the lever which in turn applies force to the drive pinion and meshes with the flywheel.
Therefore, starters are used in high-power electric motors.
Hence, the correct option is (A) high-power electric motors.

Note:
Earlier engines were started with various other methods like human power techniques, wind-up springs, etc.
The hand crank method was most commonly used but it was inconvenient and dangerous.
While starting the behavior of the engine was unpredictable. It can kick back or start to reverse rotating.
Due to various drawbacks in earlier used methods, starter was first developed by H J Dowsing in England.
Clyde J. Coleman invented the first electric starter in America and patented it.
A spring starter stores potential energy which is used in a crank to start an engine. Spring starters are used in engines that do not have a battery or alternator.
