What does a series mean? | When you have several restores and you can connect them to each other to make serval different circuits. |
What is the equation for the rate change flow. | Current= charge passing ____________ time |
The flow of one coulomb/seconds equals.. | One coulomb/seconds= 6.4 billion electrons |
Electrons are always a what? | A charge. |
An amphere is.. | 1 C per second, a way to measure electrical currents. |
Voltage is the potential of what? | The potential difference that produces electronically currents. |
The flow of charge is due to what? | The voltage difference which is called potential difference. |
Does current flow threw a circuit? | YES |
A dry cell is.. | A voltage generating cell having an electrolyte in the form of moist paste. (Might be wrong!) |
A wet cell is.. | A primary cell having a liquid electrolyte. (Might be wrong!) |
What do you measure resistors in? | Ohms. |
For given voltage the flow will........ | Be greater in a large fat wire, and less in a skinny wire because voltage is across or the number of electrons passing through a section of a wire. |
What does electric current mean? | When something starts with a positive system and then goes to a negative system. |
An amphere means? | The flow of 1 C per second. |
Voltage means? | An electromotive force or potential difference expressed in volts. |
What does electric resistance means? | The resistance of a material to the flow of electronic currents thought it measured in ohms. |
What Ohms Law say? | Ohms law is the law stating that the direct current flowing in a conductor is directly proportional to the potential difference between two ends of a cuircet. |
If you increase the resistance can you decrease the current? | YES. |
If you double the resistance can you half the current? | YES. |
What are the equations for current, voltage, and resistance? | I= V/R V= IR R= V/I |
What does i mean? | i means current (for some reason?) |
