Answer: A is the answer, The use of headings in boldface type leads the reader to specific information.
Explanation:
The three load contacts connected between the three-phase power line and the motor close to connect the motor to the line. The normally open auxiliary contact connected in parallel with the two Start buttons closes to maintain the circuit to M coil when the Start button is released.
Answer:
Explanation:
The functions of the following are as follows:
1). Oil Rings:
- Regulates oil within cylinder walls.
- Helps to keep cylinder walls lubricated
- Prevent Heat transfer
- Reduce friction between piston and cylinder
2). Fly Wheel:
- It is used to store rotational energy
- It resist any change in rotational speed due to its moment of inertia
- It helps to control the orientation of the mechanical system
3). Timing gears:
- It provides synchronization in the rotation of crankshaft and the camshaft so as to provide proper valve opening and closing time during each cylinder's stroke(intake and exhaust).
Answer:
12 volts
Explanation:
The voltage ratio is equal to the turns ratio.
secondary/primary = 20/200 = v2/120
v2 = 120(20/200) = 12
The secondary winding voltage is 12 volts.
