Circuits
1. Electric Current
- current
- amperes
- conventional current
- Current (
) measured in A - In a steady current, the total current into an object is equal to the total current out of it.
- In a wire, current moves towards lower potential.
"Current flows downhill."
2. Batteries
- batteries
- emf
- schematic symbol
- power supplies
3. Resistors
- resistance
- resistors
- ohm's law
4. Power
- watts
- Power (
) measured in watts (W)
5. Junction Rule
- junction
- kirchhoff's junction rule
- Current in = current out
6. Loop Rule
- kirchhoff loop rule
- tally method
- circuit element
- The total change in potential around a closed loop in a circuit is zero.
7. Equivalent Resistance
- terminals
- equivalent resistance
- series
- parallel
for resistors in series
(for resistors in parallel)
8. Resistance Reduction
- resistance reduction
