charged electrons are useless if they don’t have a circuit to travel on. A circuit is a system that is made of three different components and they are: an energy source‚ a load or resistor‚ and a conducting wire‚ but there is the option to use a switch. Each component has a different role in a circuit. An energy source is the source of the energy‚ the load or resistor is what uses the electricity‚ the conducting wire is what connects the circuit‚ and if you use the option of a switch you can stop

of the circuit so it could be clearer. Also the energy that comes out is a renewable energy system. Introduction/Theory: parallel circuit: a closed circuit in which the current divides into two or more paths before recombining to complete the circuit. Conventional house wiring systems are made up of parallel circuits—it’s the normal wiring mode for most electrical systems. The main energy supply can be the utility grid or a renewable energy system. The energy comes into a main circuit panel‚

Wire Ampacity and Size 1. Maximum loading for any branch circuit is 80% of rating of circuit for ampacity of wire for any load. NEC 220-2‚ use NEC 310-16 for ampacity. This applies to not more than 3 phase conductors in 1 conduit. Warning Voltage Drop NEC 310-16 wire ampacity tables do not take into account voltage drop‚ only thermal limit. Overhead triplex‚ use 310-16 for wire ampacity. Rule of Thumb If circuit is loaded up to ampacity and distance to load is around 100 feet

It is easily to determine the transformation of networks using the formula of delta and wye connection. II. Introduction Standard 3-phase circuits or networks take on two major forms with names that represent the way in which the resistances are connected‚ a wye connected Network which has the symbol of the letter‚ Υ (wye) and a Delta connected Network which has the symbol of a triangle‚ Δ

Op Amp Circuits The operational amplifier‚ or op amp as it is commonly called‚ is a fundamental active element of analog circuit design. It is most commonly used in amplifier and analog signal processing circuits in the frequency band from 0 to 100 kHz. High-frequency op amps are used in applications that require a bandwidth into the MHz range. The first op amps were vacuum-tube circuits which were developed for use in analog computers. Modern op amps are fabricated as integrated circuits that bare

SYSTEM Basic circuit Alarm Interface: We used LDR to detect Laser Light. LDR pin was Fed to Op-Amp input leg. Clock pulse to 4017 was taken from Op-Amp output pin. Light Dependent Resistor (LDR) LDRs or Light Dependent Resistors are very useful especially in light/dark sensor circuits. Normally the resistance of an LDR is very high‚ sometimes as high as 1000 000 ohms‚ but when they are illuminated with light resistance drops dramatically. Which acts as an sensor for our circuit.
