If my resistance is 10, and my voltage is 30, what will my current be?
3 A
Measured by an ammeter
what is Current?
What is the ideal wire assumption?
The assumption that the wires used in the experiment are perfect and do not cause any loss in voltage.
How tall is Daniel radcliffe?
5'5"
A circuit with only a source and no load connected
what is a short circuit
When writing out the answer to a math question, what is all the information that should be shown?
Describe the purpose: * to find the resistance
Write the equation: * v = R x I
Isolate the unknown: R = V/I
Substitute the values with units: 4V / 2A
Calculate the results: 2R
State the conclusion: The resistance is 2R
True
What is a dependent variable?
The factor being tested in the experiment
How tall is the tallest tree in the world
380.3 ft or 115.92 m
On a battery (an example of a load), Which side do the electrons flow from?
the negative side.
If you increase the voltage to 7 volts and the resistance is 4 ohms then what would the current be?
1.75 A
Should the current on a simple circuit always be the same at all points?
Yep
What is an independent variable?
The factor changed in an experiment
Who is the fastest dog in the world as a right now?
a whippet named Revenant.
Why does the bulb light up?
Electrons from the current push/bump into the atoms of the lightbulb. This causes them to transfer some of their energy to the atoms, resulting in the bulb lighting up.
If you multiply these two together then you will get the voltage of your circuit. What are they?
Current and Resistance
Which of these always measures a difference?
Voltmeter
When making a graph, where does the dependent variable go?
On the Y axis
