Circuits

In series, Amperage remains constant. In parallel, Amperages are added.

In physics, the formula for tension in a string or rope is T = mg + ma, where T is the tension force, m is the mass of the object, g is the acceleration due to gravity, and a is the acceleration of the object. This formula takes into account both the weight of the object and any additional forces causing acceleration.

Bell Labs- a branch of AT&T pre-Breakup, alternately Western Electric- another Bell subsidiary was tasked with their research and development into practical telephony one fission-product was the now universal touch-tone dial system replacing the rotary dials.

The amount of electrical pressure in a circuit is measured in volts (V). It represents the potential difference between two points in the circuit and is responsible for pushing the electric current through the circuit.

Impedance represents three types of opposition to current flow: resistance that dissipates energy as heat, capacitance that opposes changes in voltage, and inductance that opposes changes in current by storing energy in a magnetic field.

Resistors can burn out due to excessive current flowing through them, which causes them to overheat and fail. This can happen either due to a component failure in the resistor itself, or as a result of external factors like a power surge or incorrect circuit design.

Heat sinks are needed for transistors passing large currents.

Waste heat is produced in transistors due to the current flowing through them. If you find that a transistor is becoming too hot to touch it certainly needs a heat sink! The heat sink helps to dissipate the heat by transferring it to the surrounding air.

The rate of producing waste heat is called the thermal power, P. Usually the base current IB is too small to contribute much heat, so the thermal power is determined by the collector current IC and the voltage VCE across the transistor:

P = IC × VCE

The heat is not a problem if IC is small or if the transistor is used as a switch because when 'full on' VCE is almost zero. However, power transistors used in circuits such as an audio amplifier or a motor speed controller will be partly on most of the time and VCE may be about half the supply voltage. These power transistors will almost certainly need a heat sink to prevent them overheating.

Power transistors usually have bolt holes for attaching heat sinks, but clip-on heat sinks are also available. Make sure you use the right type for your transistor. Many transistors have metal cases which are connected to one of their leads so it may be necessary to insulate the heat sink from the transistor. Insulating kits are available with a mica sheet and a plastic sleeve for the bolt. Heat-conducting paste can be used to improve heat flow from the transistor to the heat sink, this is especially important if an insulation kit is used.

A clipping circuit works by the switching action of a diode when it is used in a circuit with a source voltage that changes polarity.

In the forward direction, the diode's voltage is added to any dc value that is in series with it. If the source voltage is greater than the dc value at a particular instance, the diode will limit the output to the dc value. Otherwise the output voltage will equal the input voltage.

Divide Watts by Volts ; this gives you Amps.

A short circuit occurs when an unintended connection is made between two points in an electrical circuit, causing a low resistance path for the current to flow. This can result in excessive current flow, overheating, and potentially damaging the circuit components. Short circuits are typically identified and resolved by locating and fixing the unintended connection.

1: Resistors are manufactured with different tolerances, ie they're allowed to be both a bit above as well as below the target value. 2: If you're using a simple multimeter there's no telling how close the measured value is to the real value anyhow, once that you get down to the decimal places.

The voltage drop across a resistor is equal to the resistance times the current flowing through it. If you do not have a constant current load you cannot use a resistor and must use an active solution. Please read up on ohms law before continuing with your project.

Electrical Conductivity- is the ability of a material to conduct electricity. ( in other words, it tells you what conducts electricity with what.) - your welcome,signed, really smart girl

The four probe method involves using four electrical contacts to measure the resistivity and conductivity of a semiconductor sample. By applying a known current and measuring the voltage drop across the sample, the band gap can be indirectly determined by analyzing the temperature-dependent resistivity data. The band gap of the semiconductor can be inferred by observing a change in resistivity at a certain temperature range, corresponding to the activation energy required for electrons to jump from the valence band to the conduction band.

move something by turning to kinetic energy

... that's it for me :)

In ua741 ua stands for nothing it is just the name of the ic ... Like every person have a name it similar to that one .UA is to show that the ic is manufactured by Fairchild. It is actually μa.

No, Lauren Holly is not in "Crank: High Voltage." The film stars Jason Statham, Amy Smart, and Dwight Yoakam, among others.

Steven's first novel's success propelled him onto multiple talk shows.

The old capacitor was very swollen and looked like a soda can that had been repeatedly shaken up. Be sure to write down which wires go to what terminal on your capacitor before removing the old one or just take a few pictures. For home air conditioning systems that use dual run capacitors they will have 3 terminals. The terminal labeled "HERM" is for the yellow wire that goes to the "Hermetically Sealed" compressor. The "FAN" terminal gets connected to the brown wire that goes to the condenser fan. Finally the "COM" terminal is for the purple and red wires that go to the contactor and provide power to the capacitor.

Once started the fluorescent tube no longer needs the starter. In fact starters are designed to electrically "remove" themselves from the circuit when the fluorescent tube is conducting.

An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.

A circuit can be arranged in either a series or parallel configuration. In a series circuit, the components are connected in a single path, so the same current flows through each component. In a parallel circuit, the components are connected in multiple paths, allowing different currents to flow through each component.

Variable resistor. The value of the variable resistor can be changed at any given moment.
