When powering an op-amp from a single voltage source should vss- and common ground be connected?
It depends on what you're trying to do. If you need a comparator or a trigger, then, no. If you're using it for audio or some other type of AC signal, then you need to set up a 1/2 vcc. reference to allow the op-amp to swing from plus and negative voltages.
Since the op-amp is a voltage controlled device, you can use a coupe of resistors in series, one from the plus rail and one from the negative rail, connecting the "ground" reference to the junction of the two. Just about any value will work as long as they're matched values. Try using a couple of 100 k. resistors or you can even go up to 470 k, if you really want to keep the current limited.
Bear in mind though that there are applications where offsets are needed, but without knowing your particular applications' requirements, there's not a lot of advice I can give you.
What else can I help you with?
Does line to ground voltage always half the value of line to line voltage?
Line to Ground voltage = line to line voltage / 1.73AnswerIt depends what configuration is being measured. In the case of the secondary of a split-phase distribution transformer used to supply residences in North America, the answer is yes. In the case of a star (wye) connected secondary distribution transformer used to supply residences in Europe, no: the line to ground voltage will be as described in the first answer.
Is short to voltage the same as short to ground?
No, short to voltage and short to ground are not the same. A short to voltage occurs when a component is connected directly to a voltage source, bypassing the normal circuit path, which can lead to excessive current flow and potential damage. In contrast, a short to ground happens when a circuit connects directly to the ground reference point, potentially causing a fault condition that can also lead to damage. Both scenarios can be hazardous, but they affect circuits differently.
Why substrate in nmos connected to ground and pmos connected to vdd?
In CMOS technology, the NMOS transistor's substrate is connected to ground to prevent parasitic effects and ensure proper operation, as it helps maintain a lower threshold voltage for the NMOS. Conversely, the PMOS substrate is connected to VDD to keep its threshold voltage stable and ensure that the PMOS operates correctly in the enhancement mode. This arrangement minimizes unwanted channel formation and enhances performance by reducing leakage currents in both types of transistors.
Does voltage on ground mean open ground?
Voltage on ground can mean an open ground. It can also mean (high) current on ground, due to a ground fault such as reversed neutral and ground.
How do you wire a dual potentiometer?
To wire a dual potentiometer, first identify the three terminals on each pot: the first terminal is the input (usually connected to the voltage source), the second terminal is the wiper (output), and the third terminal is the ground. Connect the input terminal of both potentiometers to the voltage source. Then, connect the wiper terminals to your output device, and finally, connect the ground terminals to the common ground. Ensure that the wiring matches the desired function, such as volume control or tone adjustment in audio applications.
In a circuit what is zero volt rail?
A zero volt rail is a rail that is connected to 0V... What do you think it is? The 0V rail is often used as a common ground, although obviously it relies on your ground voltage being 0V.
A potentiometer can act as a voltage divider?
Yes. One leg is connected to ground, the other leg is connected to the input, and the tap is the output.
It is defined as the common reference point in an electric circuit from which voltage is measured?
A Neutral, Common, or Ground.
Where do the wires go from the voltage regulator?
The wires from a voltage regulator typically connect to three main points: the input voltage source, the output load, and the ground. The input wire brings voltage from the power source to the regulator, while the output wire delivers the regulated voltage to the connected device or circuit. Additionally, a ground wire is usually connected to provide a reference point for the voltage levels. Proper connections ensure the regulator functions effectively, maintaining stable voltage output.
What does the term common refer to when discussing electricity?
A common ground is a connection between an electrical device and a conducting body, such as the ground, which is taken to be at zero voltage.
Why is it that when you touch the neutral in a box that is not connect to the panel cause the test light to come when touching the power wire?
It shouldn't. The open end of a non connected neutral should have the same potential as the voltage feeding the circuit. The only time a voltage will show is when the return neutral is tested with a meter to the neutral bar or the ground return bar. It will then show what the supply voltage to the connected load is. Once this neutral is connected to the neutral bar there will be no voltage shown across the test meter between the neutral and the neutral bar or the ground bar.

What do you mean by common emitter configuration and biasing pnp transistors?
A common emitter BJT transistor has the emitter ground. So u measure input voltage at base with respect to the ground, i.e; emitter and also u measure the output voltage at collector with respect to the ground, i.e; emitter. Hence, the emitter is common and thus the name.
Is short to voltage the same as short to ground?
No, short to voltage and short to ground are not the same. A short to voltage occurs when a component is connected directly to a voltage source, bypassing the normal circuit path, which can lead to excessive current flow and potential damage. In contrast, a short to ground happens when a circuit connects directly to the ground reference point, potentially causing a fault condition that can also lead to damage. Both scenarios can be hazardous, but they affect circuits differently.
What is the maximum voltage a man can be beared?
I was connected many time at 440 V DC, but I stood at full ground, and I'm still alive.
Does the common wire hook up to ground on thermostat?
No, the common wire (often labeled as C) does not hook up to ground on a thermostat. Instead, the common wire provides a continuous 24V power supply from the HVAC system to the thermostat, allowing it to operate properly. Ground connections are typically separate and used for safety, while the common wire is essential for powering the thermostat's electronic components.
What is the difference between source driver and sink driver?
A source driver applies voltage to a ground (common)-referenced load. A sink driver grounds one side of a load which is already connected to the supply voltage. Given the same family of drivers, sink drivers generally have the greater current drive capability of the two.
