Electric currents when connected to a potential difference, it creates a(n) _ field which creates a(n) _ force setting _ in motion
electric, electrical, charges
What do batteries and generators have to do to charge carriers?
What do batteries and generators set up across a circuit?
a potential difference
Batteries convert what to what?
chemical PE to electrical PE
Generators convert what to what?
mechanical energy to electrical PE
Do batteries and generators give the circuit charges?
Since batteries and generators don't give the circuit charges, the just...
force the charges to move in one direction *note, the electrons are already on the wire
Electrons flow from (positive/negative) to (positive/negative)
negative to positive
The electrical force _ the electrons to/from the positive terminal and the electrons are _ to/by the negative terminal
Electrons move from an area of (high/low) electric potential to an area of (high/low) electric potential (AKA voltage)
How does the flow of current in batteries work?
The negative terminal loses negative charge and eventually becomes positive. The positive terminal gains negative charge and eventually becomes neutral. Once the charges even out, there is no longer a potential difference between them, and the flow of electrons (current) stops
The direction that positive charges would flow (if they did flow)
conventional current, positive to negative
Which way does conventional current flow?
from positive to negative
The direction that electrons (negative charges) would flow
Actual current, negative to positive
Which way does actual current flow?
from negative to positive
Do you know how to draw pictures of both conventional flow notation and electron/actual flow notation?
The opposition to the flow of current in a conductor
The higher the resistance, the _ current can make it through
What is the symbol for resistance? Unit?
R, Ohms (Ω)
Put in a circuit to control (slow) the flow of current
