How do you change a parallel circuit into a series circuit?
-- Disconnect all the things that are hooked together in the parallel circuit.
-- Put them back together in one long string ... so that there's only one path
all the way from one end of the string to the other end.
Construction of mosfet in depletion region?
To make a depletion MOSFET, the channel must be doped with carriers; this is in total opposite to an enhancement MOSFET which avoids carriers in the channel at all cost. (because the carriers in the channel become the subthreshold leakage current)
Since you need to pinch the channel against the substrate to guarantee to turn off the channel completely, there must be a reverse bias between the substrate and the source terminal. As a result, the source terminal of an N type depletion MOSFET must be tied to Vdd. This is also a complete opposite to enhancement MOSFET.
In order to turn off the channel quickly, the carriers in the channel of depletion MOSFET are usually planted shallowly. This is a drastically different from enhancement MOSFET that carriers must be planted deeply into source terminal in order to support a large diffuse current.
The construction of depletion MOSFET thus requires far less diffusion time than enhancement MOSFET.
Why superposition theorem is useful for analyzing multiple source circuits?
Superposition is a useful method when dealing with multiple sources. Instead of the more math oriented methods like nodal and mesh analysis, it provides an intuitive and more obvious solution by cancelling the effects of all sources except one and then solving as if it were one circuit with that single source. Doing the same for the other sources and then adding all of the results together gives you an easier method rather than dealing with massive calculations.
What is the purpose of capacitor in power supply higher than rated voltage?
The voltage marked on a capacitor is its MAXIMUM SAFE WORKING VOLTAGE.
The capacitor will work in a circuit at any voltage lower than that, but it may
fail at any higher voltage.
Explain how you would modify the 8 bit adder circuit in Figure 3-20?
I'll get started on that just as soon as I have a look at Figure 3-20.
Is the neutral conductor of a two wire single phase circuit considered a current carrying conductor?
Sure. In a two-wire circuit, both wires carry equal currents.
2.2 megohm resistor to amperes?
The question does not make sense. Ohms is a unit of resistance, while amperes is a unit of current. The two are not related unless a third item is given, such as volts. Please restate the question.
A 2000watt heater draws 8amps What is its rated voltage?
Power = (current) x (voltage)
2,000 = 8 V
V = 2,000/8 = 250 volts if the power factor is ' 1 ' and everything is operating as marked
DC Resistance = 0.1362 Ohms/km
Reactance depends upon line configuration and spacing
What is a circuit path called that has a break in it preventing current from flowing?
That's an "open" circuit.
Which electrical voltage value does a dmm output when in diode test mode?
When testing a diode with dmm in diode test mode 0.6v is delivered through the device to indicate continuity
A device that creates a potential difference in an electric circuit is?
It is called power supply or battery.
NMOS PLA is a Programmable Logic Array which is designed by employing NMOS technology i.e. by employing nmos transistors to realize the required gates of PLA.
PLA is a combination AND gates and OR gates to produced sum of products terms needed for realizing the required combinational logic. It consists of an array of AND gates followed by OR plane. the connections to the AND and OR inputs can be programmed based on our needs.
Full Data(FD) circuits are copper circuits used to transmit low grade data through a network. Most applications (but not all) are in the utility industry. For example the water company will use an FDDA to transmit the level of a well back to their monitoring station and if the level is too low, the operator can tell the well to pump through the receive side of the circuit.
Swamping resistor is made up of?
Swamping resistor is mostly made of manganin or constantan because these materials have temperature coefficients very close to zero thus there is a very less change in the resistance of these materials with change in temperature.
