The purpose of a resistor is:
to provide access to the circuit without any breaks in the electrical flow.
to provide a precise amount of electrical resistance in a circuit.
The following image is a schematic symbol of a resistor:
T or F: Resistors are necessary for slowing down the flow of electrons.
True
False
T or F: When a resistor conducts electric current, its temperature will decrease.
True
False
A device that allows current to flow through it in only one direction is known as a:
Motor
Switch
Diode
Ohms law states that
It's time to end class.
a standard color code associates each color with a specific decimal digit (0 - 10)
that current in a circuit is equal to voltage divided by the resistance.
a resistor conducts electric current.
T or F: Ohms law states that voltage in a circuit is equal to resistance times current.
True
False
T or F: Circuit resistance typically decreases due to poor connections,loose connections,corrosion,damaged components
True
False
Changing a circuits resistance changes the amount of ____________ flowing through the circuit
True
False
Divided by
Current
Ohms Law
I = VR where V=Current and R is resistance
V=IR, where I =Voltage and R is Current
R = V/I where V =Voltage and I is resistance
V=IR, where I =Current and R is resistance
