Electricity Unit

Resistor

Things like light bulbs/appliances that use electricity and slow the electricity down, by converting it into light/heat energy

Electric field

The battery creates an electric field in the wires when it exerts a force that pushes electrical charges around the loop.

Voltage Change

Voltage level on the + battery side minus the voltage level on the - battery side

Voltage

Pressure or energy level of the charges

Current Rate

The amount of charges passing every second (Amps)

What is Ohm’s Law

Voltage Change across a resistor equals the current through it times its resistance

As a charge goes through a resistor it ____ voltage.

Loses

How many paths for current in series circuit

1

Current changes or stays the same in series circuit

Stays the same

Voltage stays the same throughout a series circuit or does it change

it changes, as it goes through each resistor, voltage in the charge decreases

In which circuit does the charge have to go through every single resistor one by one

Series

Is resistance smaller than one indiivual resistor in series circuit or parallel?

Parallel

How to find resistance for a series circuit

Add each resistor up

How many paths for a parallel circuit

multiple

What does current do in a parallel circuit

Splits up but equals the amount you start with

In a parallel circuit the flow of charges splits up, 4 Amps might go some way, the other 2 Amps go another way BECAUSE THERE ARE MULTIPLE TYPES OF RESISTOR OPTIONS

What gets changed in a resistor

voltage, it drops

How do you find the equivalent single resistor for parallel circuit

1/Req parallel = 1/R1 + 1/R2 + 1/R3….

Units for resistor

Ohms
