100
The working part of a battery.
What is the electrolytic cell?
100
The definition Lighting
What occurs because of a difference in charge between a cloud and the ground, a cloud and another cloud, and a difference on charges between one cloud?
100
The continuos flow of electrons
What is current electricity?
100
A fuse.
What is a device that limits the amount of electrical current flowing througha circuit?
100
A semiconductor device with two electrodes that only lets current flow in one direct.
What is a diode?
200
How do the wet cells and dry cells differ from each other?
The wet cell contains a liquid electrolyte, which is free to flow and move. While, the dry cell works like the wet cell, but it uses a combination of thick, paste-like chemicals for the electrolyte.
200
These three things are used to control the flow of electricity.
What are fuses, switches, and circuit breakers.
200
This is what drives electrons through a wire.
What is voltage?
200
This happens when the switch is open and there is a break in the circuit .
What is an open circuit.
200
A series of 1s and 0s.
What is a binary code?
300
The two kinds of electrolytic cells.
What are wet cells and dry cells?
300
The word "Static" meaning
What is stay?
300
The current that flows in one direction.
What is Direct Current
300
The three parts of a circuit.
What is the power source (such as a battery), a load (like a light bulb, and a condutor or wire to connect these parts together.
300
Descibe the funtions of photocells and solar cells.
What is Photocells use light to generate or control an electric current, and solar cells are electronic devices that change solar radiation directly into electricity.
400
The three parts of an electrolytic cell
What is the electrolyte, the positive terminal, and the negative terminal?
400
What happens when there is a lose of electrons.
What is a lose of electrons would cause a positive charge?
400
How does a shorter thicker wire affect the resistance of an alectric current.
What is it provides less resistance.
400
This will happen if you add multiple loads to a parallel circuit.
What is the loads will receive the same amount of power, as if there was only one load.
400
BLANK are tiny chips of silicon that control electric current.
What is BLANK:microchips
500
Three advantages of single use batteries, and three advantages of rechargeable batteries.
Single-Use: *Less expensive first cost than rechargeable batteries *Ready to used, you don't need to wait for charging *Dependable amount of charge *Less likely to explode or start a fire Rechargeable: *Long term cost savings *Produce less waste *Less toxic than single-use batteries
500
The cause of lightning.
What is positive charges are more common at the top of the cloud where ice and snow form. The heavier, negativly charged water molecules drop lower in the cloud. The negative charges at the base os the you are attracted towerd the gound below. When the difference on the charge becomes great enough, a giant spark is released through the air.
500
Silver is a better conductor that aluminum. If a silver wire and an aluminum wire have the same length and the same thickness, which will have a hight resistance.
What is silver would have the least resistance, because it is a better conductor.
500
The difference between a parallel circuit, and a series circuit.
What is a series citcuit flows in a single path, while a parallel circuit is when the circuit is devided into several branches so the current flows into multilple paths?
500
How transistors work
What is a small sandwich of two different types of semiconductors that hanges it's conductivity as it works. They mainly act as switches or gates and use the binary code.
