What happens when you reverse the current in a current-carrying magnetic field?
The polarity of the electromagnet reverses.
Will Changing the polarity of a vacuum cleaner's plug cause it to blow instead of suck?
No. you cant change it's polarity because electrical current that a house uses is not a + - type, it changes it's polarity 50 times per second.
How do appliances work if AC reverses direction?
AC current alternates polarity back-and-forth continually, by definition. Therefore, it is not possible to reverse AC direction. It is DC current that is directional such that when it's polarity is reversed the motor responds by turning in the opposite direction.
Is alternating current a current type where electricity flows in the positive direction only?
Alternating current changes polarity 50 0r 60 times a second depending on the country you are in.
Electron current flow theory considers electricity to be the flow of charge carries which are what in polarity?
When we consider electron flow, we think of moving electrons. The electron has a negative charge. This model of current flow, the electron current flow model, follows the movement of those negative charges.As a contrast, we might consider what is called conventional current flow. And that the model of current involves the movement of charges with a positive polarity.
Which current is having high polarity?
ac(Alternating Current ) has the high polarity.
Explain welder polarity?
Welder polarity has to do with DC (Direct Current) welders. Essentially, polarity is the direction of the current. Straight polarity means that the current is running from the electrode, to the metal, and back through the grounding clamp. Reverse polarity means that the current is going the opposite way, from the grounding clamp, through the metal, and up through the electrode.
Will changing the polarity of the current change the polarity of the electo magnet?
Yes!
What rule is used to find out polarity of a current carrying solenoid?
right hand rule is used to find out the polarity of current
What is polarity in welding?
Polarity in welding has to do with the direction of the current in the welding process. With direct current (DC) the welding circuit can either be straight, or reverse polarity. When the machine is set for straight polarity, the current flows from the electrode to the weld surface and creates considerable heat in the metal. When the machine is in reverse polarity, the current is backwards and is flowing from the metal to the electrode causing a grater concentration of heat at the electrode.
What is alterneting current?
a current that keeping on changing its polarity with time is called alterneting current
How do you tell polarity?
what do ya mean by "Polarity" for the following parameters? Charge: Voltage: Current: Meter Probes:
Does a diode have polarity?
Yes, a diode inherently has polarity, as current is only allowed to flow one direction.
Does Direct current have constant amplitude and polarity?
yes
The polarity of an electromagnet is determined by what?
the direction of the flow of current
What happens when you reverse the current in a current-carrying magnetic field?
The polarity of the electromagnet reverses.
The what of an electromagnet is determined by the direction of current flow?
The electromagnet (polarity) is determined by the direction of current.
