When charging an object by conduction what happens to the charges in the object
Electrons move onto the object, giving it a static charge.
Apex ;)
How is the wiring done in houses and other occupied buildings
It is in parallel, so one light can be on while others are
turned off.
Electric field lines point in the opposite direction charges would move if they were in the field
When electric and magnetic fields both exist it is called an
According to Coulombs Law how does distance affect the electric force
electric force can act at a distance bbut is stronger when
object are closer
In a series circuit the is the same at every point
In a series circuit the current is the same at every point. This
is Kirchoff's current law.
If an electric circuit is not grounded it is best to reach out and touch it to provide the ground
No. Touching a live electric current is never a good idea.
A 120 V power supply connected to a 30 ohm resistor will produce how many amps of current
A 120V power supply connected to a 30 Ohm resistor will produce
120/30 or 4 amps of current.
The current in a what circuit is the same at every point
The current in a series circuit is the same at every point.
Which data-storage device will not have its data scrambled by a magnet
A hospital has a back-up generator to power the medical devices in case of a power failurewhat is the most likely source of mechanical energy for the generator
gasoline or diesel fuel...apex
What will be attracted to or repelled by an magnet
a copper wire carrying current and another magnet.
Can electric fields be seen by the human eyes
Electric fields are invisible, and cannot be seen.
