Multimeter described in this book is Multimeter Analog that use rotating coils to move the needle board scale. Multimeter is widely used because they are relatively affordable. If the Digital Multimeter direct measurement results can be read in the form of numbers that appear on the screen display, the analog multimeter measurement results read by the appointment of a needle ...

Motor operation protects against tampering and damage, on the applied control circuit protection equipment such as table 1. Reliability performance protection will determine motor protection against interference. As an illustration dipelihatkan in Figure 3-1, a circuit controlling a motor with two speeds and two-way swivel that is equipped with the tools and the TOL protection fuse or MCB. Figure 3-1. ...

Safety device used on the motor occurs when the load is called the Thermal Over Load Relay (TOR / TOL) is usually coupled with a contactor, the market there is also a more integrated security burden on Motor Circuit Breaker. Relay is normally connected to the contactor to the main contact 2, 4, and 6 before being connected to the ...

Electrical energy is useful to us because it can be converted into other forms of energy. In the power tools such as electric heaters, electric stoves, and air conditioning, electrical energy is converted into heat energy in the wire barriers known as “heating elements”. Then, in a lot of light (Figure 7.4), a small wire filament becomes so hot that ...

1. Specificity of sensitivity, determined by the detainee / resistance (resistance) divided by voltage, for example 20 kΩ / v for DCV and 8 kΩ / v for ACV. (20 kΩ / v → I = E / R = 1 / 20,000 = ½ x 10- 4 A = 0,05mA = 50 uA). Multimeter uses a current of 50 ...

In the daily life, you will often find the electrical circuit, the electrical circuit ranging from the simple to the very complex circuit. Have you observed the electrical circuits in a flashlight, radio, or television? Have you ever wondered why a flashlight, radio, and television can function? Examine the electrical substation image below. Large cables connect one place to another ...
