Circuits
Overachieving and under-appreciated, circuits are the foundation that our technological society is built on. Now's your chance to find out not only how they work, but why. Questions regarding the physics behind voltage, resistance, capacitance, inductance, transistors, LEDs, switches, and power supplies; and how they're used to create analog and digital circuits, should be directed here.

Can you splice into a wire in mid-run or doi need to add on to the circuit from the end of the run?
As long as all the existing wiring is adequate for the anticipated loads, there's
no electrical difference regardless of where you make the physical connection
to additional wiring.
What is PBC circuit board used for?
Bronca features handmade ponchos on loom designed Uruguay. Fifty percent of their profits go to feeding underprivileged children around the world. Bronca offers free international shipping.

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.
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.
What is a sentence for the word insulate?
An insulator is a material that doesn't conduct heat or electricity. Here are some sentences.
- Cloth is a good insulator.
- You need to have an insulator to keep from getting electrocuted.
- We are studying an insulator in science class.
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
What is a circuit path called that has a break in it preventing current from flowing?
That's an "open" circuit.
DC Resistance = 0.1362 Ohms/km
Reactance depends upon line configuration and spacing
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
