CP1 REVIEW TOPICS Flashcards
Types of units
Volts
Amperes
Ohm’s
Kirchoff’s Voltage law
It is a series circuit
Kirchoff’s current law
Parallel circuit
Series circuits are
Total current is the same as the current in each resistor
That’s some of the voltage drops across each resistor equals the total of the supply voltage.
Take net supply voltage (if polarities opposite)
Parallel circuits are
Sum of the current in each leg is equal to the total current
Voltage across each resistor is equal to the net supply voltage
Series are
Parallel circuits
Electrons flow and conductors only and go from
Negative to positive
Conventional current flow is opposite
(+ve to -ve)
A corrosion cellis made up of
Anode, cathode, electrolyte ,conductor
Ionic transfer in
Electrolyte
Ohm’s law
V(voltage)=IR
I(current) -=V/R
R(Resistance)=V/I
Ionic transfers in
Electrolyte
Atoms, molecules, ect
Atoms, molecules,ect
Oxidation is a loss of electrons at the
Anode
Reduction is
A gain of electrons at the cathode
