What else can I help you with?
Why negative control is adopted in DC system And why DC circuit breakers are kept at the negative side?
The answer is: They are not. Whosoever told you that is off his meds. Alternatively, in some special applications there may be a reason for it. Many DC systems use a common ground where the loads are encased in the ground (like starter motors). Thus all breakers are positive, but some don't. If the loads don't care about polarity and the positive and ground are not common (like with a metal chassis), positive and negative is irrelevant.
Does a charged capacitor block DC or AC or both?
It blocks DC or it wouldn't be charged. It passes AC through it to ground or it wouldn't filter. But in the early days charged electrolytic capacitors were used as rectifiers or AM detectors.
Why is a dc motor not earthed?
A DC motor is typically not earthed to prevent ground loops and minimize interference with the motor's operation. Earthing could create unwanted return paths for current, potentially leading to erratic performance or damage. Additionally, many DC motors are designed with insulated windings, which means they do not require a ground connection for safe operation. Instead, they rely on proper insulation and design to ensure safety and functionality.
How does a filter operates in DC power supply?
It removes the remaining AC ripple after the rectifier, using capacitors (to bypass it to ground) and/or inductors (to block it).
If you have an air solenoid valve DC and the wires are Green Black and White. Which one is positive and negative?
Green= Ground Black = live White = Neutral
What color is green positive or negative for DC?
green is ground regardless of ac or dc
How do you get -48v DC?
In a 48V DC system you ground the positive to 0V so the live wire will be -48V.
How do you ground in dc circuits. I've seen many circuits around the net with plus ve terminal from the battery and no -ve terminal to the battery and ground symbols.. wat to do in these circumstances?
The physical body of your DC Equipment is always your GROUND. This GROUND is where you also connect your -VE.
What is a ground loop isolator?
Ground loop isolators are used to break the DC circuit path for the audio shield ground circuit. It removes ground loops from the system, which are unwanted.
What is the difference between ac ground and dc ground In your project iam using both ac and dc supply can both the grounds or the return paths be connected?
In principle you can use a common wire for ac and dc in a low voltage low power circuit, for example 12 volts at up to about 20 watts. If the ac is at a power-supply voltage it must use separate wiring to comply with safety standards. In low-power dc equipment like radios it is normal to use a step-down transformer with the ac live and neutral connected to the primary, and the earth connected to the transformer case, the chassis and one side or other of the dc supply taken from the secondary via a rectifier and smoother.
What causes a meter to read negative voltage across a DC motor?
The main cause for a meter to read negative voltage across a DC motor is a loose ground wire. The ground wire can be loose or may need to be cleaned.
What electrical systems are the current standard for cars?
12 volt DC Negative ground.
Flying time between Florida and DC?
For direct flights, about 1.5 hours flying time from Orlando to DC. This is time 'in the air' and excludes ground activities.
A DC ground wire coming from a power supply output is typically what color?
Typically black. DC +ve wire color typically red or brown.
How can a test light be used to test for power and ground.?
Testing for 12V DC power using a 12V DC test light, clip the test lead to a known ground (preferably battery negative post) then probe with the test light tip for power. Test light will illuminate when power is touched.Testing for 12V DC ground, clip the test lead to the positive post on the battery then probe with the test light for grounds. Test light will illuminate when a ground is touched.
What pins go to power load and ground on a bridge rectifier for building a DC power supply?
The two pins with the ~ symbol are for the AC input and the + and - are for the pulsing DC output
What is ac ground?
If a circuit is grounded through a capacitor it is referred to as AC ground because ac signal can pass through the capacitor DC level is blocked
