Electric Charge and Force
Atoms that are not neutral, meaning they are positively or negatively charged
What are ions?
ELECTRIC FIELD LINES show the direction of the electric force, and the field lines point toward a negative charge and away from a ______ charge.
what is a positive
A material that doesn’t allow electrons to move easily
What is an insulator?
The number of electrons that pass a given point in a certain amount of time.
What is an electric current?
the term that states the relationship and interaction between the voltage, current, and resistance in a circuit.
What is Ohm's law?
When atoms acquire more _______, the atom is NEGATIVELY CHARGED.
What are electrons?
An area around an electric charge that experiences the force exerted by that charge.
What is an electric field?
material that is good at transmitting energy because it is made of a material through which electrons move easily.
what is conductor
A continuous flow of the charges that can travel in a closed conducting loop
What is a electric circuit?
Something that measures how hard it is for electrons to move through a current.
Type of an attractive and repulsive force
What is an electric force?
true or false larger the field larger the charge
what is true?
Something that repels the flow of electrons but still lets them through
What is a resistor?
A type of a current where charges move one way the entire time
What is a direct current?
The measurement for resistance
What are ohms?
Static Electricity is when an ______ ____ builds up and transfers from one object to another body.
What is an electric charge?
What are electric field lines?
Copper is a bad insulator true or false
What is false?
A circuit in which the electron can only move one way and all the currents flow in one direction through the elements.
What is a series circuit?
True or False: If voltage increases then current, resistance, or both will decrease
What is false?
The size of an electric force depends on how charged the atoms are and _______________
What is their distance?
the opposite type of molecules in an electric field
What is a positively charged molecule?
A material that is good at transmitting energy because it is made of a material through which electrons move easily
What is a conductor?
A circuit in which electrons take more than one path.
What is a parallel circuit?
The formula in Ohm's law
What is Voltage = current x resistance?
