Unit 1 Electronics

Electrons are a _ charged particle

negatively

electrons are attractive to

positive charges and repel negative ones

Voltage is the force that

moves electrons

Series Circuts

an electron flowing through one component must flow through the other

Series Circuits voltage

will divide between components

Sereies circuts current

is the same through all components

how should a current meter be connected in a series circut?

needs to be connected in series

Parallel Circuits

electron can move through either two components to end up at the same new point

Parallel Circuits Voltage

each branch of circuit has the entire voltage applied at the source

Parallel Circuits Current

Splits to add up total current from source

Direct Current (DC)

electrons that move in the same direction all the time. Voltage stays the same

Alternating Current (AC)

electrons moving in one direction, then the opposite direction, and repeating. (sine wave) voltage is changing

Vpk

Peak Voltage

Vpk-pk

highest Peak to lowest peak

Vrms (Vpk/√2)

magnitude of a varying quantity

solve Vpk

Vrms x √2

Voltage meter is connected in

parallel

Is it possible to have voltage without current?

it is possible to have voltage without current but not current without voltage

Electrons Flow

Clockwise

Current flows

counter clockwise 

If voltage in a circuit increases and current is flowing.

current will increase

Electrons will always move from a more ____ charge to a more ______ charge

negative, positive

what will allow current to flow the easiest?

Conductor

In order for current (electrons) to flow in a circuit there must be

voltage and a closed circuit

What is the force that causes electrons to move

voltage

Which of the following are required for current to flow in a circuit?

Circuit must have a path from the one side of the voltage source (through the circuit components) to the other side of the voltage source.There must be a voltage source properly connected to the circuit.

Electrons flow easier through a

conductor

Power Equation

P = V x I

The voltage of the source in a circuit is _________ equal to the load voltage drop.

always

If an electron must move through one component to get to another component in a circuit.

The two components are connected in series.
