What is static electricity?
The accumulation of excess electric charge on an object.
Most objects will be neutrally charged, but when one object rubs up against another object, electrons are transferred between the two and both become charged.
True or False.
Electrons move more easily through conductors.
True
What is current electricity?
The continuous flow of electrons through a circuit.
What is Ohm's Law? (Accurately draw the triangle for me. Include: V, I, & R)
/ v \
/ I | R \
V -> Top
I & R -> Bottom
What is a large scale example of static discharge?
Lightning (kachow)
What are the two types of electricity?
Static and Current
What are the types of current electricity?
Direct Current & Alternating Current
What does each variable in Ohm's Law represent?
(V, I, & R)
V = Voltage
I = Current
R = Resistance
What are 3 ways an object can gain/transfer a charge from/to another object?
Friction, Induction, Conduction
What is the Law of Conservation of Charge?
Charge may be transferred from object to object, but it cannot be created or destroyed.
What is a direct current?
A type of electric current where the charges flow in one direction only.
What is the voltage of a circuit if the current is 4 amps and the resistance is 3 ohms?
12 volts
What is the definition of friction?
Charges that result by objects rubbing against each other.
What is the definition of electrical insulators?
Materials that resist the flow of electric current.
What is an alternating current?
A type of electric current that flows in one direction, then the reverse direction, repeatedly.
What is voltage measured in?
Volts
What is the definition of conduction?
Charges that result by direct contact between objects.
What are 2 examples of electrical insulators?
Rubber, glass, plastic, wood, paper
What is current measured in?
Amperes (amps)
What symbol represents what resistance is measured in?
Ω (ohms)
