| So something that would supply Electricity, is also Suppling what? | -Energy. The Electric Current Transfers Energy via the Power Supply. |
| How does Electric Circuits really Work? [Involving Energy] | -Energy is given [Supplied] to a Charge at the Power Source, to 'Raise' it Through a Potential. [Like a Ski Lift]
-This Charge will give its Energy away when it 'Falls' through a Potential Drop, in any Components. |
| If a Battery has a big Voltage, [Potential Difference] what would Happen to the Circuit? What about a Component with a High Resistance? | -The Battery will give More energy to the Circuit Every Coulomb of Charge, which will flow around it
-The Charge is Raised 'Higher' and can Transfer More energy in the Circuit
-The Component with a High Resistance will need More Energy for the Charge to Transfer to Pass Through, its a Higher Drop in Potential Difference. |
| What is Power [In Circuits] | -This is simply the Rate of Energy Transfer |
| What does the Power of a Component Tell you? Give the Formula for your Answer | -This tells you How much Energy it can Transfer per Second
-Power [P] = Energy Transferred [J]

......................Time [s] |
| What is a Kilowatt Hour? Give me the Formula for Power using Kilowatt Hour as a Unit | -This is really the Amount of Energy a Device [With a Power of 1kW or 1000W] Transfers in a Hours Operation.
-Power [kW] = Energy Transferred [kWh]

............................Time [h, Hours] |
| How can you find out the Electrical Power of a Component? [Using pD and Current]
Can Resistance be added for the Formula? | -This can be done from the Potential Difference across the Component [in Volts], along with the Current passing it [in Amps] The formula is Below
-Power [W] = Potential Difference [V] x Current [A or I]
-Since you know Ohms Law {Potential Difference [V] = Current [A or I] x Resistance [Ω]} that means we have another way of getting Power. Formula is Below
-Power [W] = Current² [A or I]² x Resistance [Ω]
or
-Power [W] = Potential Difference² [W]²
