__________ is the difference in charge between two points.
_____________ is the rate at which charge is flowing.
_____________is a material's tendency to resist the flow of charge.
A circuit is a _____________ loop that allows charge to move from one place to another.
The amount of potential energy between two points or the difference in charge between the two points is called _____________.
_____________ is the amount of charge flowing through the circuit over a period of time.
Current is measured in __________. (Full word)
What is the unit for describing the amount of resistance in a circuit? (Full word)
1 V = 2 A * 2 Ω
What is the keyboard shortcut used to get Ω?
I'll give you a hint. It begins with ALT+??? What's the number?
Example - Power is an electrical quantity and it is represented in equations using the letter P. It's base unit is Watts and is represented after quantities with W. I can describe the power a lightbulb uses as P = 40 W.
Match the electrical quantity (voltage, current, resistance) with its base unit symbol (what you put after a number:
| Stavka koja se može prevući | arrow_right_alt | Odgovarajuća stavka |
|---|---|---|
Resistance | arrow_right_alt | V |
Electrical potential difference | arrow_right_alt | A |
Current | arrow_right_alt | Ω |

What should should happen to current in a circuit if voltage remains the same and resistance increases?
What should a circuit designer do to make an LED brighter in a circuit while keeping the same total voltage in the circuit?
You must place a resistor in before an LED in order to control the amount of current going to the LED. Putting a resistor after the LED will have no impact and will cause the LED to burnout.
