Concord Consortium: Total Resistance for Resistors in Series
Use the tutorial to find the total resistance for resistors in a series circuit.
Concord Consortium
Concord Consortium: Calculating Voltage in Series Parallel Circuits
Use the series and parallel resistance formulas to determine the total resistances of the parts. Then, use Ohm's Law to calculate the voltage drops across each part.
Concord Consortium
Concord Consortium: Total Resistance for Resistors in Parallel
See how this application of Ohm's Law leads to a formula for the total of parallel resistances.
