- Ohm's Law
- V = IR
- Capacitor Equation
- Inductor Equation
- Kirchoff's Laws
- Kirchoff's Voltage Law (KVL)
- Summary: The sum of all the voltages around a loop is equal to zero.
- Kirchoff's Current Law (KCL)
- Summary: At any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node.
- Kirchoff's Voltage Law (KVL)
Resistors in series or complicated resistor networks can be replaced by one single equivalent resistor, REQ or impedance, ZEQ and no matter what the combination or complexity of the resistor network is, all resistors obey the same basic rules as defined by Ohm’s Law and Kirchoff’s Circuit Laws.
REQ = R1 + R2 + ... Rn

1/RT = 1/R1 + 1/R2 + ... 1/Rn = (R1 * R2 * ... Rn) / (R1 + R2 + ... Rn)
To be equivalent, two schematics must:
- Represent every component and source
- Have the same number of nodes
- Each node must be connected to the same branches
- Place inputs on the left, and outputs on the right.
- Let information flow from left to right across the circuit.
- Use up/down on the page to suggest voltage levels. That is, draw higher voltage wires closer to the top of the page, and lower voltages (like ground) near the bottom of the page.
A passive component is one that does not amplify a signal. We say that current goes into the positive side or travels in the direction of positive to negative.
