Characteristics of Electricity

What type of energy does a battery contain?
1. Electrical potential energy
2. Electrical kinetic energy
3. Electrical difference energy
4. Electrical volt energy
The earliest batteries were sometimes called "piles". Why did they get this name?
1. The earliest batteries were stacks of alternating metal discs
2. The first batteries were made from materials from piles of garbage
3. The constructed batteries were very weak so they had to be piled up on top of each other
4. "Pile" was the middle name of the inventor, Alessandro Volta
A voltmeter is a device that measures potential difference. Consider the following four batteries that are connected to voltmeters.

Which of the following batteries is connected to a voltmeter in a way that will provide a proper measurement of voltage?
1. Battery Y
2. Battery W
3. Battery X
4. Battery Z
Which of the following best describes the difference between wet cells and dry cells?
1. Wet cells have a liquid electrolyte, while in dry cells the electrolyte is a moist paste
2. Dry cells have a liquid electrolyte, while in wet cells the electrolyte is a moist paste
3. Wet cells have liquid terminals, while in dry cells the terminals are a moist paste
4. Dry cells have liquid terminals, while in wet cells the terminals are a moist paste
What creates the potential difference between electrodes in a wet cell?
1. Negative charge building up on one electrode, and positive charge building up on the other
2. Negative charge builds up on both electrodes, but more negative charge building up on one electrode than the other
3. Positive charge builds up on both electrodes, but more positive charge building up on one electrode than the other
4. A build-up of neutral charge on both electrodes
Shanice builds a wet cell using two zinc electrodes and an acid electrolyte. She connects a voltmeter to the wet cell, but it reads zero voltage. What is the most likely reason for the zero reading on the voltmeter?
1. Two different metals are necessary for a potential difference to form
2. Shanice should have used copper electrodes instead of zinc
3. The acid electrolyte was not strong enough
4. Voltmeters cannot measure the voltage of a wet cell
The amount of voltage produced by an electrochemical cell depends on
1. the types of metal and the electrolyte used in the cell.
2. the amount of electrolyte used in the cell.
3. the amount of water in the cell.
4. the temperature of the cell.
Which of the following devices converts heat into electrical energy?
1. Thermocouple
2. Solar panel
3. Piezoelectric crystal
4. Electrochemical cell.
All batteries have end points where electrical connections are made.

These end points are known as
1. terminals.
2. electrodes.
3. cells.
4. plates.
Which of the following would be best choice as a source of electricity for an orbiting space station?
1. Solar panels
2. Electrochemical cells
3. Thermocouples
4. Water-powered generators
