| A | B |
|---|
| energy loss | all stages of energy conservation loses some useable energy |
| electromagnet | can be strengthened by increasing the number of coils around the iron core |
| tungsten | used in light bulbs because it is a resistor- heat and light |
| geothermal energy production | uses heat of the earth to make electricity |
| hydroelectricity | floods land and creates methane gas |
| thermoelectric generation | creates greenhouse gases, nonrenewable energy source |
| thermonuclear energy production | creates radioactive waste that lasts for many years |
| electrical energy in joules | power in watts x time in seconds |
| parts of a circuit | load, source, switch, conductor |
| microcircuit | has all parts in mini; switch is called a transistor |
| wet cell | has metal electrodes and liquid electrolyte |
| electrode | must be 2 different metals to work |
| electrolytes | must be ionic solution or acid to work |
| parallel circuit | has more than 1 pathway for electron flow |
| series circuit | when 1 part breaks, the whole circuit stops |
| battery | 2 or more cells; the more the stronger the voltage |
| ammeter in amperes | measures current; put device in series |
| voltmeter in volts | measures voltage; put device in parallel to load |
| circuit breaker | safety feature; bimetallic strip |
| fuse | safety device; metal that melts when too hot |
| resistance in ohms | voltage divided by current |
| energy efficiency | percent; joules divided by joules x 100 |
| heat and light | two products of a resistor, always |
| current | flow of electrons |
| voltage | energy or potential difference behind electrons |
