200

an accumulation of charge

What is static electricity?

200

State the equation for Ohm's Law

V= I x R

or I = V / R

200

What are three ways static electricity accumulates?

Induction, conduction, and friction

200

What are the two types of circuits we learned about?

Series and parallel

200

A disturbance in space and time that carries energy from one place to another

What is a wave?

400

When electric charge moves in an electrically conductive substance, such as metal

What is conduction?

400
What do the three variables (I, V, and R) in Ohm's Law represent?

I = Current

V = Voltage

R = Resistance

400

What does the word "static" actually mean?

It's Greek for "standing still" or "at rest"

400

What is a series circuit?

A circuit in which all of the resistors are in the same loop of wire, one after another

400

Any wave requiring a medium to propagate

What is a mechanical wave?
600

moving electric charge

What is electric current?


600

If V= 6V and R = 5.5 Ohms, find I

I = V/R = 6/5.5 = 1.09A

600

What is the opposite of a conductor?

An insulator

600

What is a parallel circuit?

A circuit in which each resistor is in its own branch an the branches are connected together at the ends

600

A scale measuring how acidic or basic a substance is

What is pH?

800

a substance that does not conduct electricity

What is an insulator?

800

What is the unit of measurement for current (I)?


Amperes (A)

800

Describe an example of induction

(answers may vary)

800

What is a junction in a parallel circuit?

The place where two wires are connected together

800

Energy that is stored and can be released by conversion into s different form of energy

What is potential energy?

1000

When the presence of nearby charges causes the charges in a nearby object to crowd together

What is induction?

1000

If I = 0.096 A and R = 125 ohms, find the voltage (V)

V = I x R = .096 x 125 = 12 V

1000

Explain how lightning forms

(answers may vary)

1000

What is a schematic diagram?

An abstract diagram that clearly represents the devices in an electrical circuit and how they are connected.

1000

Continuous, periodic movement back and forth or up and down

What is oscillation?
