Electrical Fields 1
The strength of an electric field is determined using this equation.
What is E =Force/charge (E = F/q)?
Electrical potential difference is measured using this device.
What is a voltmeter?
This is the SI unit for electrical potential difference?
What is the volt?
A volt can be written as this derivative of two SI units.
What is Joules/Coulomb?
This is the SI unit for electrical potential?
What is the Joule?
A constant electrical field can be produced using this setup.
What is two parallel plates with equal and opposite charge?
This is the SI unit for capacitance?
What is the farad?
This is the equation used to calculate the capacitance of a capacitor.
What is capacitance (C) equals charge divided by voltage (C = Q/V)?
This is where electrons are distributed on a solid conductor.
What is evenly throughout the entirety of the object.
Capacitors have these two functions.
Capacitors can be used to smooth out electrical impulses or to turn constant electric currents into a series of impulses.
This device is composed of a pair of parallel plates, separated by a small distance.
What is a capacitor?
The SI unit for field strength (aka electric field intensity) is this.
What is Newtons/Coulomb?
This is the strength of the electrical field inside a charged, hollow, metal sphere.
What is 0 N?
This is where charges reside in a hollow conductor?
What is evenly distributed over the surface of the hollow object?
This occurs when electrons are equally distributed over a charged surface due to the repulsions of the electrons to other electrons.
What is charge sharing?
The electron concentration of the Earth is this compared to many objects.
What is less?
The third, round wire on many modern plugins functions as this.
What is a ground?
The chains dragging on the road on many big fuel trucks function to do this.
What is to prevent the build up of static charge by grounding the truck?
The area of force produced by an electric charge is known as this.
What is an electric field?
This is the voltage a capacitor can reach before it discharges and allows the voltage across the capacitor to drop to zero and current to cross the gap.
What is capacitance?
The work required to move a charged particle from one place in an electrical field to another in the same field is known as this.
What is electrical potential?
This is the equation used to determine electrical potential?
What is Work = Voltage/distance (W = V/d)?
This is the difference in difference in electrical potential between two points in an electrical field.
What is electrical potential difference?
This is the equation used for calculating electrical potential difference.
What is volt equals electrical field intensity € times distance (V = E*d)?
This occurs when a charged substance touches the grounds and the electrons are redistributed evenly between the original object and the ground, leading to an overall reduction in the concentration of electrons on the object.
What is grounding?
