Electricity definitions
The resistance or opposition to the flow of charge
What is resistance?
A measurement that has a magnitude and a direction
What is a vector?
Divide force by area
How do you calculate pressure?
Must always be connected in parallel around a component
How should a voltmeter be added into a circuit?
1/2mv2
A material that does not allow charge to flow
What is an insulator?
The direct (in a straight line) route from one position to another
What is displacement?
What is Newton's 2nd Law?
They would repel each other
If 2 like charges were brought together, what would happen?
Pa or Nm-2
What are the units for pressure?
The rate of flow of charge
What is current?
The amount of matter in an object
What is mass?
Calculate the gradient of the graph
Divide voltage by distance between the plates
How do you calculate electric field strength between 2 charged plates
NC-1 or Vm-1
What are the units for electric field strength?
A region/area where a charged object experiences a force
The rate of energy transfer
What is power?
Calculate the area underneath the line on the graph
How do you calculate the distance travelled using a velocity-time graph?
The total resistance of the circuit would increase
What happens if you add a component in series?
OR
What happens if you remove a component in parallel?
Increase the height above the ground, or mass of the object
How do you increase the gravitational potential energy of an object?
The work done per unit charge
What is voltage?
A force that opposes the direction of motion
What is friction?
The amount of matter in an object and the gravitational field strength that the object is within
What does weight depend on?
If a component breaks in a branch, the other branches will continue to receive charge flow
What is an advantage of a parallel circuit?
Js-1
What is an alternative unit for power?
