How do you determine the terminals of integrated circuits LM 7808?
A: I could tell you but it is better if you learn how to do it on your own look up datasheetlocator.com LM78XX . For these numbers there are SOT-223 and TO-252 and TO-220. These numbers specify packaging You probably have TO-220 in that case looking from the top left is adj vout vin. The metal can be Vout again it depends on the packaging use a VOM to ascertain the metal tab connection.
If V in battery voltage equals 5volts Resistor 1 equals 6ohms and Resistor 2 equals 4ohms What will be the volt meter Vout read?
4.5 Volts
How can you produce 5 volt in voltage regulator having IC LM 2941CT?
Put a voltage divider between Vout and Vadjust pins. See page 9 of the datasheet from National's site.
How output voltage is out of phase in CE?
It should be ~180 degrees out of phase, because a CE amplifier is an inverter. A BJT CE amplifier is a good example to look at. The output is across CE, and at a minimum total output voltage is split across CE and some resistor R. As a higher voltage is applied to the base, the current flow through CE increases as a result of the resistance of CE decreasing. This boils down to a simple voltage divider at the output, Vout = CE / (R + CE). As CE decreases as a result of the input increasing, Vout will decrease.
Why self bias is known as self?
Self biasind is called self because in this biasing, the variation due to change in temperature increases the the collector current, which hence decreases the output voltage i.e Vout=VCC-ICR and maintains the stability
Does anyone have a simple method for calculating the parameters of a network comprising a capacitor in series with a capacitor that is in parallel with a resistor?
I am assuming this configuration: -----------|Capacitor 2|----------|--------|------- | | Vin [R] [C1] Vout | | | | ------------------------------------------------------- 1. Using the Laplace transformer, C1 impedance equals 1/ sC1 (similar for C2). 2. Then treat C1 as you would a resistor to reduce the network: For two parallel resistors, the combined resistance = R1*R2 / (R1 + R2) Zparallel R and C1: R*1/sC1 / (R + 1 / sC1) = R / (RsC1 + 1) 3. Then to determine how the input varies from the output, Vout / Vin, using voltage divider Voltage divider for two resistors: Vout = Vin * R1 / (R1+R2) For the above: Vout = Vin * [R/RsC1 + 1] / ([R/RsC1 + 1] + 1/sC2), If you do a little manipulation, you will get: Vout = Vin * RsC1 / (RsC2 + RsC1 + 1)
In electronic devices what are the factors that determine the voltage gain of an amplifier.?
The amplification factor Vout/Vin determines the voltage gain.
Why do some regulators need a heatsink?
Most linear regulators absorb the amount of energy equal to (Vin-Vout)*I where Vin is the voltage into the regulator, Vout is the regulated output voltage, and I is the current flowing through the regulator. This energy is dissipated as heat. As to much heat will burn the device out, a heatsink is needed where the die of the device cannot adequately dissipate the waste heat into the atmosphere.

What PIV rating is required for the diodes in a bridge rectifier that produces an average output voltage of 50 V?
Its 50-0.7=49.3V Using this Formula : PIV Rating = Vout - 0.7V
What is a v out?
"Vout" typically refers to the output voltage of a circuit or device. It is the voltage level that is generated or present at the output terminal or node of the circuit. Voltage output is a common measurement parameter in electronics and electrical engineering.

What is the voltage gain of the FET amplifier?
It can be answered in two ways : 1. ratio of output & input voltages [Vout / Vin] i.e Drain voltage(Vds)/Source voltage(Vs). 2. multiplication of trans-conductance & drain resistance .
Why self bias is known as self?
Self biasind is called self because in this biasing, the variation due to change in temperature increases the the collector current, which hence decreases the output voltage i.e Vout=VCC-ICR and maintains the stability
