In a switching DC-DC voltage converter, the oscillatory nature of the switching circuit generates a small "ripple" effect in the output voltage which is supposed to be minimized via careful design of the overall circuit. The output current of this type of converter typically flows through a diode into the rest of the system. The voltage measured at the cathode of this diode will exhibit the aforementioned ripple.

I assume you are asking about inductors... The inductor has a winding, sometimes around a ferrous core. Current flow creates a magnetic field. When you try to change the current, the magnetic field changes, but that magnetic changing resists the change in current. Mathematically, this is expressed as di/dt = v*L, or Rate of change of Current is equal to Voltage * Inductance. So, the larger the Inductance, the harder it is (requiring larger Voltage) to change Current.

ANSWER: one way tie a zener x volts from B+ to ground with a resistor. that gives you a reference voltage using an PNP tie the base to the reference voltage collector goes to the load and the emitter is tied to +B trough a resistor Since the emitter follows the base then the current should be +B volts -zener voltage - Vbe or .6 v. that is it.

A short circuit is an unexpected path of zero resistance between two nodes in a circuit. If you measure the resistance of a resistor, and find that is has zero ohms, but the resistor is supposed to be somthing else, such as 100 ohms, then you can conclude that the resistor is shorted. Keep in mind that the precision of the measurement might be critical. If the resistor is supposed to be 100 ohms, but you get zero ohms, then the answer is easy. If the resistor is 0.001 ohms, but you get zero ohms, then you have to consider the precision of the measurement, the resistance of the wires, etc.

Telephone exchanges were built in the days before electronics and it was found that the sheathing of lead telephone cables suffered less corrosion from water when the exchange battery was connected with a negative earth.

When polyethylene sheathed cables and electronics arrived in the 1950's this problem was lessened. The first PNP germanium transistors were suited to this polarity but when silicon transistors appeared in the 1960's the most popular NPN types were suited to negative Earth. It has remained this polarity to the present day.

haptic technology or haptic feedback is used on touch screens. not all touch screens have this feature and as of now only certains types can have it. haptic feedback is when you press down on a touch screen and the device will vibrate to show a button is being pressed.

forcing a constant current and measuring the voltage across the unknown resistor.

If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC

It is a horizontal line of ladder logic.

Ladder logic is a language used to program PLC's.
It's called Ladder Logic because the programs are formed in the shape of a ladder. Each horizontal line in the program looks like the "rung" of a ladder, which is why they call it Ladder Logic.

The capacitor in which only a specific number of electric lines or electrons can pass through a unit area is called as 'Flux Capacitor'

There are no vacuum tubes in a transistor. A vacuum tube is an electronic device that uses a heated cathode in a vacuum to direct and control an electron stream to an anode, also known as the plate. The vacuum tube is old technology, but it is still used today, typically in high power applications such as transmitters. A transistor is an electronic device that uses solid-state semiconductors to similarly control an electron stream. The transistor is newer than the vacuum tube. It offers lower power, smaller size, easier use and other enhancements over vacuum tubes, within limits, of course, such as voltage and power.

As frequency increase the wave length decreases like a beam of light it cannot bend therefore directional

Go up, then stop as it burns out if you push it too far.

Make sure the the Leeds are inserted in the right hole. Make sure that the meter is set to the range of voltage or current you expect

The 4027 master-slave filp-flop is a pair of CMOS edge triggered flip-flops connected in series. Assuming that you don't assert the set or reset inputs (which are overrides) the first flip-flop will follow the input on the leading edge of the clock, with the other following on the trailing edge.

A: Due to undesirable external voltage changes like the AC line dropping out occasionally the DC or input signal will become a variable voltage that is referred as voltage fluctuation but it can refers to all kinds of these kind of problems.

1 volt applied across one ohms Will conduct one Ampere

A circuit diagram, or schematic, is a picture of how the components in a circuit are connected together. Using the diagram, you can perform analysis of the design. You can also use it to troubleshoot a fault in the circuit.

When a circuit is said to be resonate it means a signal or wave that is being generated has some relationship with a reflected or feedback signal such that the generated signal is reinforced with the reflected or feedback signal. This reinforcing of the signal may cause a standing wave of constructive interference and required the generation of the signal and the reflection or feed back to be in phase or Coherent. if there is no phase coherency then it can be harder to achieve the standing wave of constructive interference. However is the Phase is detected and delay is compensated it can be achieved like in a laser ring gyro, which uses two resonate cavities that have there path length adapted to cope with heat expiation.

The equivalent of an inactive Thevenin voltage source is a source with zero voltage between its terminals regardless of the current through it, best represented by a zero resistance, i.e. a short-circuit. The equivalent of an inactive Norton current source is a source through which no current can flow regardless of the voltage across it, best represented by an infinite resistance, i.e. an open circuit.

In telecommunications, facility refers to the transport network (see http://en.wikipedia.org/wiki/Telecommunications_facility). In an optical transport network, facility would refer to the optical fibre plant. Terminal refers to the end equipment that is communicating over the transport network (see http://en.wikipedia.org/wiki/Terminal_%28telecommunication%29). Thus, in the context of optical transport equipment, a terminal loopback sends data received from the end equipment back to the equipment. A facility loopback sends data received from the transport network back to the transport network.

One kilometer is equal to approximately 0.62137 miles. Similarly, there are 1.6093 kilometers in one mile. The kilometer is metric unit used for length, and the mile is the unit of length used in the Imperial system.

Two similar (non-polarized) capacitors connected in parallel will have double the capacitance of one, while two similar capacitors connected in series will have half the capacitance of one, so the ratio is four.
