Series Circuits

Series circuit

circuit that has only one path for current to flow

Chassis ground

ground connection to the case of a piece of equipment

Circuit breakers

device designed to open under an abnormal amount of current

Earth ground

ground established by driving a rod into the earth

Fuses

devices used to protect a circuit or electric device from excess current

What happens to a fuse when there is too much current

a metal link will melt, this will open the circuit

Ground point

point at which a grounding conductor is attached

Voltage drop

amount of voltage required to cause an amount of current to flow through a certain resistance

Voltage polarity

polarity of a voltage at a particular point in a circuit

What is true about current in a series circuit

current in a series circuit is the same at any point in the ciruit

Fuses and circuit breakers are connected in _____ with the rest of the circuit

in series

Sum of all voltage drops in a series circuit equals

the total applied voltage

How is voltage drop across each resistor is related to the resistance

voltage drop is proportional to the resistance of the resistor

What is true about thetotal resistance in a series circuit

the total resistance in a series circuit is the sum of resistances in the circuit

What are voltage dividers used for

to provide different voltages between specific points in a circuit

A chassis ground is used as a

common connector for other parts of a circuit

A chassis ground goes to the ground, yes or no

NO, chassis ground does not go the earth

Determiners of voltage required

amount of current flow and resistance

3 rules of series circuits

current is the same at any point in the circuit

total resistance is the sum of the resistors

applied voltage is equal to the sum of the voltage drops across all the resistors
