Kirchhoff's First Law
The principle stating that the total current entering a junction equals the total current leaving the junction.
Ohm's Law
The relationship between voltage (V), current (I), and resistance (R) defined as V = IR.
Series Circuit
A circuit configuration where resistors are connected end-to-end, so the total resistance (RT) is the sum of the individual resistances.
Parallel Circuit
A circuit configuration where resistors are connected across the same two nodes, and the total resistance (RT) can be found using the formula 1/RT = 1/R₁ + 1/R₂ + 1/R₃.
Voltage Division in Series
In a series circuit, voltage across each resistor is proportional to its resistance according to Ohm's Law.
Current Division in Parallel
In a parallel circuit, the current through each branch is inversely proportional to the resistance of that branch.
Total Resistance (RT) in Series
The total resistance in a series circuit is calculated by RT = R₁ + R₂ + R₃ + …
Total Resistance (RT) in Parallel
The total resistance in a parallel circuit is calculated as 1/RT = 1/R₁ + 1/R₂ + 1/R₃ + …
