Resistance and current are __________ proportional.
directly |
|
inversely |
|
not |
|
exponentially |
Resistance is opposition to the flow of current and is measured in ohms (Ω). One ohm is defined as the amount of resistance that will allow one ampere of current to flow if one volt of voltage is applied. As resistance increases, current decreases as resistance and current are inversely proportional.
Resistance is measured in:
amperes |
|
coulombs |
|
volts |
|
ohms |

You would measure the amount of resistance at a certain point in a circuit with a(n):

A diode to an electronic circuit is like a _______________ to a city?
highway |
|
parking lot |
|
one-way street |
|
traffic light |
A diode allows current to pass easily in one direction and blocks current in the other direction.
The volt is a unit of measurement for:
power |
|
capacitance |
|
current |
|
voltage |
Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.
