Q

Difference between Conventional current and Electron Flow?

A

Both theories.
One from Benjamin Franklin, electricity flows from Positive (+) to Negative (-), Conventional Current.
Joseph Thompson, electricity, from Negative (-) from to Positive (+)

Q

What are special about AC transfomers?

A

They allow the change of Voltage in the circuit

Also allows for the transport of electricity over long distances

13
Q

Say Amps, instead, why?

A
Not practical to say:
"Coulomb per second"
Or
"Quadrillion Electrons"
so we just say Amp

Q

Where does a Resistor’s wasted energy go?

A

Out and away as Heat!

17
Q

Fuse(s)

A

Small inner wire, rated to handle a certain amount of current

18
Q

Circuit Breakers

A

A switch that opens to break the circuit, to prevent overload and protect the devices on the circuit

19
Q

What does more Voltage allow?

A

More Voltage = More Current

20
Q

Potential Difference

A

How much can be potential done by circuit

21
Q

Battery boosted?

A

If another battery is added in Series, and Voltage is boosted

22
Q

Battery in Parnell?

A

Voltage stays the same

23
Q

Voltage and Volt are Different!

A

Voltage - pressure

Volts - the Units used to measure the pressure in

24
Q

DC Circuit

A

Series, Parallel, Parallel & Series

25
Q

Resistance in Series Circuits

A

R(T) = R(1) + R(2) + R(3) + R(N)

26
Q

Current Formula(!)

A

Current (A(amps)) = Voltage (V(volts)) / Resistance (Ω (ohms))
