What is the difference between an open and closed circuit?
A closed circuit has no break in it and is on.
An open circuit has a break in it and is off.
The wiring in your home typical uses what type of circuit?
Parallel
Materials through which current will not easily flow are called:
Insulator, Conductor, Semiconductor
Insulator
A capacitor is a device that:
Stores electrical energy
As the distance between 2 positively charged objects increase, the force between them
Decreases
Draw a circuit diagram using two lightbulbs a battery and a switch.
Check with teacher.
Kirchoff's CURRENT law applies to a parallel circuit because it states that:
All current flowing into a branch point must flow out again.
The electrons in an insulator are best described as...
In a fixed place
When a capacitor is discharged while connected to a circuit with little resistance, it can create a large amount of ________
current
An electric current in a metal consist of moving:
Electrons, Protons or Neutrons?
Electrons
In an electrical circuit, a voltage difference is what.....
supplies energy to make charges flow
The total of all voltage drops in a series circuit must...
Add up to the total voltage supplied by the battery
Because of Benjamin Franklin's work, the direction of current in an electrical circuit is defined as going from _________ to __________
Positive to negative
A capacitor can be charged by a ___________
battery
Positive electric charges: ________ positive charges & _______ negative charges
Repel; attract
The flow of charge particles in wires, motors, light bulbs, and other devices is called electric ________.
Current
What is the basic difference between series and parallel circuits?
A series circuit contains one path for the flow of charge; a parallel circuit contains more than one path
When more devices are added to a series circuit, the total circuit resistance ________
increases
The amount of charge a capacitor can store depends on 3 factors with the parallel plates. Give me 1
1. The insulating ability of the material between the positive and negative plates
2. The area of the two plates
3. The separation distance between the plates
The buildup of charge on an object through friction is called ________ electricity
Static
