Resistance
_________ is the restriction of the flow of electrons.
What is Resistance?
______________ is a component of a circuit that resists/stop flow of electric current

to measure the resistance of a circuit you would use _________
What is an Ohmmeter?
____________________ are made from finely grounded up lead, graphite, and non-conducting ceramic clay.
What are Carbon resistors?
In a simple circuit, increasing this property of a resistor makes it harder for electric current to flow.
What is resistance?
Resistors prevent this from becoming too high in a circuit.

What are Wire wound resistors?
This happens to current in a circuit when resistance is high and voltage stays the same.
What is the current decreases?
Resistors can come in many colors, and these colored bands show this important property.
What is resistance value?
Georg Simon Ohm was a German physicist who studied the relationship between ________________________________
