What is the primary difference between the LM317 and LM337 regulators based on electrical engineering?
Both are 1.5A adjustable voltage regulators. The LM317 outputs a positive (with respect to ground) voltage, and the LM337 outputs a negative voltage.
What do ground do in a circuit?
Circuits are on the ground for a few reasons one is to prevent contact with dangerous voltage if the electrical insulation fails. Also been on the ground limits the build- up of electricity static.
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.
What is mean of Dead Short in Electrical Term?
The positive and negative voltage lines are tied together - OR - the positive line is shunted to ground with voltage appliedImproved AnswerA dead short is a connection with zero/near-zero resistance. It may be applied deliberately in order to perform tests, or, more usually, as the result of a catastrophic failure in some part/component."The positive and negative voltage lines are tied together - OR" - both lines of an a.c. supply are connected together."the positive line is shunted to ground with voltage applied" - OR - the negative line is shunted to ground, etc etc.
Does voltage flow in a circuit Explain?
Voltage in an electrical circuit is the rough equivalent of pressure in a water pipe. It causes the electricity to flow. Higher voltage; more flow. The difference is that you can think of pressure applied at a single point, but voltage is always the difference in electrical potential between two points. That's how a bird can stand on a 7,000-volt rural electrical line without harm. The potential difference (voltage) between the line and the ground is 7,000 volts, but the potential difference (voltage) between the bird's two feet is very tiny.
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.
What is a surge protector used for?
A surge protector (or surge suppressor) is an appliance designed to protect electrical devices from voltage spikes. A surge protector attempts to limit the voltage supplied to an electric device by either blocking or by shorting to ground any unwanted voltages above a safe threshold. This article primarily discusses specifications and components relevant to the type of protector that diverts (shorts) a voltage spike to ground; however, there is some coverage of other methods
What mean Frame Ground?
The frame of a device is usually the supporting structure that holds the electrical device. The electrical code requires that the frame of any electrical device be brought down to ground potential. This is done with a ground wire taken from the frame of the device and connected to the service distribution ground. This is also classed as a bond wire. Now if a fault current occurs any where in the bonded system, the fault current will travel back to the distribution panel and trip the circuit breaker of the faulted circuit removing the voltage from the faulted circuit..
What is a grounding device?
what the hell is a grounding device? Any device that allows you to affix a ground wire to the mechanical enclosure that the conductors are in. eg. Ground lugs, ground screw in an electrical box.
Does surge protectors protect against electrical fires?
surge protector designed to protect electrical devices from voltage spike. A surge protector attempts to regulate the voltage supplied to an electric device by either blocking or by shorting to ground voltages above a safe threshold.
Why can devices be damaged if you do not provided a ground to the circuit?
Devices will not be damaged if they do not have a ground conductor in their supply cable. The ground wire is there for safety. If there is a possibility that the device could conduct a current in a fault condition and this happens, it is the ground wire current that trips the breaker and shuts the supply voltage off. There is equipment on the market that is double insulated. This means that the internal electrical current carrying parts are isolated from the frame of the device. These types of devices will have only a two wire cable supplying the voltage to it.
Difference between unidirectional and bidirectional TVs diode?
Unidirectional TVS: A TVS device with asymmetrical current versus voltage (I−V) properties. A unidirectional TVS is best suited for protecting circuit nodes whose signals are unidirectional or always above or below the reference voltage, usually ground. Bidirectional TVS: A TVS device with symmetrical I−V properties. A bidirectional TVS is best suited for protecting electrical nodes whose signals are bidirectional or can have voltage levels both above and below the reference voltage, usually ground
If an electrical voltage comes in contact with your body what would be the result?
You would get a shock if you provided a path to ground.
Why voltage measurement using the oscilloscope requires only one terminal?
Because the O'scope and the device being checked must somehow be sharing a common ground. That may be good, bad, or indifferent, depending on the electrical sensitivity requirements of the device being checked. It won't harm a quality O'scope.
How do you test elec actuator?
If it's an actuator that works off an electrical circuit, apply electricity (the body of the device will be - or negative or ground if there is no - or negative or ground wire to the device)/ if it is a vacuum device, then you will need to apply vacuum to determine it it "actuates".
How do you figure out the voltage of something?
Most electrical devices are labeled with their respective voltages. If not the manufacturers website should allow access to the specifications ( you'll need the part number). Another way to determine the voltage is with a volt meter. Put he positive lead at the input of the device when it is turned on and the negative lead at the devices ground. If the device has the power and current ( watts and amperes respectively ) marked on it you can determine the voltage by using the equation; v = w / a where v is the voltage, w is the power in watts, a is the current in amperes.
Can you use a beam clamp to ground an electrical panel in an industrial setting?
No, a beam clamp is not a recognized device for grounding an electrical panel in an industrial setting.
