Hi, when a current flows through a conductor a magnetic field is set up around it, it is this magnetic field or flux that attracts your compass. This of course has practical applications such as motors or generators using tight coils of wire which when a current is passed through sets up magnetic fields, in the form of a generator these lines of flux are turned and passed to stationary coils, in a motor these fields are rotated causing the yolk or rotor to chase the rotating magnetic field giving us circular motion.

Does a 3 phase circuits require GFCI breakers when installed near a sink in a commercial kitchen?
Yes, a 3-phase circuit installed near a sink in a commercial kitchen typically requires Ground Fault Circuit Interrupter (GFCI) breakers to enhance safety. This is due to the increased risk of electrical shock in wet environments, as GFCIs are designed to protect against ground faults by shutting off power when an imbalance is detected. Local electrical codes and regulations may also mandate the use of GFCI protection in such locations. Always consult with a licensed electrician to ensure compliance with applicable codes.
Is condensation near an electrical panel dangerous?
O course it is very dangerous. Moisture should never ever be allowed near a service panel.
What is the difference between primary electrical distribution and secondary distribution?
Primary electrical distribution carries medium voltage power to distribution transformers near the customers. Secondary electrical distribution transfers the power from the transformer to the households.
When did the United States stop using DC power in your homes?
We never did, that battle was lost before electrical transmissions lines where anywhere near common.
What changes the voltage of a current?
First off, voltage and current are two completely different, yet related phenomenons.Kirchoff's law states that Voltage = Current * Resistance (V=IR. So, to change the voltage in a given circuit while keeping current constant, simply change the resistance.Open in Google Docs ViewerOpen link in new tabOpen link in new windowOpen link in new incognito windowDownload fileCopy link addressEdit PDF File on PDFescape.com
Does a compass turn near a closed circuit wire?
It will if there is current flow
Is the magnetic field that is near an electrical circuit parallel or perpendicular to the circuit?
Perpendicular to the circuit.
What are 3 conductors you shouldn't have near an electrical circuit?
# Your body # Water # Earth (ground)
Why does the compass respond when it is near a electrical wire with current flowing through it?
The compass responds to electrical currents because the flow of current generates a magnetic field around the wire. This magnetic field affects the compass needle, causing it to align with the direction of the field. This phenomenon is known as electromagnetic interference.
How a compass can be used to trace the magnetic field of the magnet?
A compass can be used to trace the magnetic field of a magnet by placing the compass near the magnet. The needle of the compass will align with the magnetic field lines, allowing you to visualize the direction of the field. By moving the compass around the magnet, you can map out the shape and direction of the magnetic field.
How could you change the direction in which a compass needle points using a cell and a piece of wire?
The compass will react to magnetic fields, and magnetic fields are caused by currents. Therefore, holding a current-carrying wire close to the compass is enough to change the direction in which it points.The compass will react to magnetic fields, and magnetic fields are caused by currents.

What do tripped circuit breaker and blown fuses indicate?
Blown fuses indicate overload in the electrical circuit. Possible short-circuit or higher input voltage.Tripped circuit breakers I guess means:A residual-current device (RCD), similar to a residual current circuit breaker (RCCB) which is used for breaking the circuit when electric current pass through a man or could cause fire/burning in the/near the electrical sockets.

What was the disadvantage of using a compss to determine direction?
A compass may give inaccurate readings if it is near a magnetic field, metal objects, or electrical devices which can interfere with its accuracy. Additionally, compass readings can be affected by variation and deviation which may need to be compensated for to determine true direction.
Should you see a fence on the compass when your near the cattle ranch?
You should never see a fence on a compass.
Why does a compass change direction when a metal is near?
When a metal object is brought near a compass, it can disrupt the Earth's magnetic field around the compass. This disruption causes the compass needle to align itself with the new magnetic field created by the metal object, resulting in a change in direction.
