DC power→ electromagnets→ Rotation → Rotating Magnetic field. The English scientist Sir Charles Wheatstone coined the word rheostat, it is derived from the Greek word “rheos” and “-statis” which means a stream controlling device or a current controlling device. What is the purpose of a rectifier in the x-ray circuit? A sliding contact in different types of rheostat is used to change the length and therefore, changing the resistance. For better risk management c. To characterize adverse effect of toxins d. To reduce probability of occurrence 2. The article describes through schematics how resistors play a vital role in electronic circuits. 2. A rheostat can also be used for this purpose, but a rheostat will have a different current. Main breaker switch. to create dc for the main generator field. share. The purpose of the game is to be able to efficiently read the instruments at night. The main purpose of a potentiometer is to measure a force that is electromotive. Cloudflare Ray ID: 60b046675a21e6b4 A potentiometer is a manually adjustable electrical resistor that uses three terminals.

In order to do that, one of the three factors (length, type, and area of cross-section) that affect the resistance will be changed and that factor is the length. If the galvanometer resistance is 20 Omega, what is the galvanometer current? Here is a typical datasheet. 87 Views. a. to provide information b. to increase primary demand c. to increase selective demand d. to accentuate a product’s value ANS: B PTS: 1 DIF: 2 REF: 401 OBJ: What is the main purpose of a resistance in a circut. (3) To plot a dispersion curve for the glass prism, and use the curve for the identification of unknown wavelengths. The resistance, R, provides the required reduction in current or the desired drop in voltage. Working exciter is known as the primary source of DC power for rotor excitation. The following text is used only for educational use and informative purpose following the fair use principles. 1. O A. to communicate a message B. to enhance functionality O C. to provide balance to a design D. to provide visual appeal 2 See answers harmonsavana harmonsavana D, to provide visual appeal. Note the current specification, so you'd need a 75W pot to keep the current within spec. It does so by having the potential difference balanced. to insure proper output frequency: Term. Ask your question. List the differt types of rectifiers? Physics glossary . D. What are collagen balls? Ask your question. In the lung, alternatively activated macrophages (AAM) form the first line of defense against microbial infection. This is an instument that allows you to vary resistance by a mechanical means. Log in. FIG I.—CRAXUI.AR r.RBON RHEOSTAT This can generally be done within limits where an alternatingcurrent is used, but the apparatus used for the purpose is some-what expensive, so that in experimental work it is often de-sirable to use merely a rheostat. Hence the whole voltage will be dropped across the first portion of the resistance, won't it? Switchboards consist of various electronic apparatus used to operate electric circuits.
