| What is Current? | -This is the Rate of flow of Electric Charges or Electrons in a Circuit.
-Current only happens [in an Electrical Component] if Potential Difference is Present, and if the Circuit is Complete [No Gaps]
-Current is Also the Rate of Flow of Charge
-Units is: Ampere [A] |
| What is Potential Difference? | -This is the Force that pushed the Current around pretty much
-Cells, Batteries and Power Supplies give that Potential Difference
-Potential Difference in an Electrical Component [Motor for an Example] is really the x Amount of Energy Transferred by That Electrical Component [This case, Kinetic Energy Store] Per Unit of Charge
-Potential Difference is often Named Voltages. Exactly the Same Thing
-Units is: Volts [V] |
| What is Resistance? | -This measures how Easily the Charge can Flow
-Units is: Ohm [Ω] |
| What happens if you have a High Potential Difference? [in terms of current] | -The Current will also follow suit [it will get Higher]
-[Usually] |
| What happens if you have High Resistance of a Component? | -The Current will be Smaller [Potential Difference will be the Same] |
| What does the Total Charge [through a Circuit] Depend on? | It relies on the Current and Time |
| Formula of Charge
Rearrange it to Time= | -Charge[C] = Current [A]x Time [s]
-Time [s] = Charge [C]

| Samantha has a Battery that has a Current of 0.25 Amps. Over 4 Hours, how much Charge does the Batter Transfer? | -First Convert the Units [4H=14400s]
-Now use the Formula [C=A x T]
-Subsite what you Know into the Formula, and Complete it [C=14400 x 0.25] [C=3600] |
| What exactly is Charge? | -Charge is simply the x Amount of Current flowing In a Current flowing Past a Point in a Certain Amount of Seconds. |
| What is the Formula of Energy Transferred?
Rearrange it to Charge= | -Energy Transferred [J or E] = Charge [C or Q] x Potential Difference [V]
-Charge [C or Q] = Energy Transferred [J or E]
