A ________ is a circuit that has one pathway for an electric current to flow through.
What is a series circuit
100

Objects with unlike charges will __________.

What is attract each other?

A __________ is a material that an electic current can not easily flow through.
What is a insulator
200
A ___________ circuit has two or more pathways for an electic current to pass through.
What is a parallel circuit

What is a switch?

A device that opens a circuit (creates a gap)when the switch is off and closes a circuit to let the electricity flow when the switch is on.

Is a coin, such as penny, a condutor or an insulator?
What is an insulator?

Why does your hair stand up when you rub a balloon on it?

static electricity

Is a rubber an insulator or conductor?

What is a insulator?

What is the difference between a series circuit and a parallel circuit?
In a parallel circuit, the parts are connected so that current passes along more than one pathway. In a series circuit, the parts are connected so that the current goes through one pathway.

What causes static electricity?

When a negative charge moves to an object that you touch and it has a negative charge and the other item now has a positive charge. The items are no longer neutral.

If I have a balloon with 4 negative charges and 6 positive charges, what will the overall charge of the balloon be?
What is positivley charged?

In a string of holiday lights, all of the lights work if one bulb is broken or removed. Use what you know about circuits to explain this.
The string must be a parallel circuit. In a parallel circuit there are two pathways for the electic current to take, this will skip over the missing socket.

What happens if your circuit is connected to two positive charges.

Positive charges repel so it needs to connect from the positive to the negative side of the battery
