Static Electricity
9 x 10 9 Nm2/C2
What is Coulomb's constant?
Series and parallel circuits.
What are two types of electrical circuits?
What is a magnetic switch?
Out of North and into South.
What is the direction the lines of force of a magnet?
What is a solenoid?
Rubber
Which material has the most electronegativity?
What is potential difference/voltage?
It only allows electricity to travel in one direction.
What is a diode?
A substance which can become magnetized when domains are aligned.
What is a ferromagnetic substance?
A wire that generates a magnetic field that wraps around it when an electrical current flows through it.
What is a straight line conductor?
It pulls electrons away from one of the objects and transfers them to the other
What is friction?
Current intensities are all equal in series and they add up to the total in parallel circuits. Potential differences add up the total in series but are all equal in parallel circuits.
What are Kirchoff's Laws?
Type of material, length of wire, diameter of wire and its temperature.
What are the four factors that affect conductance?
Opposites attract and likes repel.
What are the laws of attraction and repulsion?
A ferromagnetic substance that, when put in a solenoid, strengthens its magnetic field.
What is a core material?
The proximity of a charged object causes a partial charge in the neutral object.
What is induction?
The amount of work done over a certain period of time.
What is power?
Two types of protection found in circuits.
What are fuses and breakers?
The area of space which the magnetic force can act on another magnet.
What is a magnetic field?
The factors that influence the strength of a magnetic field in an electromagnet.
What are current intensity, number of loops and core material?
The force between two immobile and electrically charged particles.
What is Fe=kq1q2 / r2, Coulomb's Law?
It must be placed in series in a circuit; it must be placed in parallel in a circuit
A switch with two paths and one contact.
What is a single pole double-throw switch?
What is a compass?
It is used to determine the direction of lines of force by having the thumb point north; it is used to determine the lines of force by having the fingers curl in their same direction.
What is the right-hand rule for solenoids/electromagnets and the right-hand rule for straight-line conductors?
