Thermocouple – They are made of two wires (each of different homogeneous alloy or metal) which form a measuring junction by joining at one end. This measuring junction is open to the elements being measured. The other end of the wire is terminated to a measuring device where a reference junction is formed. The current flows through the circuit since the temperature of the two junctions are different. IR Sensor -This device emits and/or detects infrared radiation to sense a particular phase

found using the equation below. Current in series and parallel circuits Conservation of charge – ” the total charge flowing into a junction of wires must equal the total charge flowing out of the junction”. Kirchoff’s first law – “the sum of the currents flowing into a junction of wires must equal the sum of the currents flowing away from the junction of wires”. Current in series circuits. When you put an ammeter into a series circuit the current is the same wherever you put the ammeter

Scoliosis is diagnosed as one of three forms: idiopathic‚ which means the cause is unknown; congenital‚ which means the bones are asymmetrical at birth; or neuromuscular‚ which means the scoliosis is symptomatic of a systemic condition like muscular dystrophy‚ Friedreich ’s ataxia‚ or cerebral palsy. In this case study‚ the patient suffers from neuromuscular scoliosis because he has cerebral palsy. Some of the signs that a person suffers from scoliosis include: • A spine that curves inward or downward too

Too young to have sexual experience The squamous-columnar junction of a female usually distribute outside of the cervix when they were young. As their ages increase‚ the squamous-columnar junction will move towards the uterus. The more far away of the squamous-columnar junction‚ the more easily to infect the HPV viruses. Thus‚

called "DC" circuits. They serve as first approximations for AC circuits. Kirchhoff’s Current Law This law is also called Kirchhoff’s first law‚ Kirchhoff’s point rule‚ or Kirchhoff’s junction rule (or nodal rule). The principle of conservation of electric charge implies that: At any node (junction) in an electrical circuit‚ the sum of currents flowing into that node is equal to the sum of currents flowing out of that node‚ or: The algebraic sum of currents in a network of conductors

Basic Electronics Semiconductor —I • Materials that permit flow of electrons are called conductors (e.g.‚ gold‚ silver‚ copper‚ etc.). • Materials that block flow of electrons are called insulators (e.g.‚ rubber‚ glass‚ Teflon‚ mica‚ etc.). • Materials whose conductivity falls between those of conductors and insulators are called semiconductors. • Semiconductors are “part-time” conductors whose conductivity can be controlled. germanium Semiconductors silicon

III.8. THE TUNNEL DIODE 1. Theory The Japanese physicist Leo Esaki invented the tunnel diode in 1958. It consists of a p-n junction with highly doped regions. Because of the thinness of the junction‚ the electrons can pass through the potential barrier of the dam layer at a suitable polarization‚ reaching the energy states on the other sides of the junction. The current-voltage characteristic of the diode is represented in Figure 1. In this sketch i p and U p are the peak‚ and iv and U v are

early devices were made in the same way as a point-contact diode‚ although today’s devices are made with totally different manufacturing techniques. Unlike conventional semiconductor diodes‚ which consist of a PN junction‚ the Schottky diode is made from a metal semiconductor junction. This offers a number of advantages in some circumstances as the diode has a very low forward-voltage drop‚ and secondly it has a very fast switching speed. Both of these properties make it ideal for many RF applications
