Current Electricity
I = Q / t
Q: total charge, Units: Coulombs (C)
-
I: current, Units: Amps (A)
V = E / Q
V: voltage, Units: Voltage (V)
E: energy, Units: Joules (J)
Q: charge, Units: Couloms (C)
Series
Current goes through a component, So Ammeters always connect in series
-
-
Parallel
Voltage goes across a component, so Voltmeters always connect in parallel
-
-
-
Ohm's Law
V = I x R
-
-
R: resistance, Units: Ohm
-
Current: Flow of charges, though a circuit
-
-
Conductors: Materials that have lots of free electrons that are free to flow through the material
(metals have a 'sea' of electrons)
