Concord Consortium: Calculating Current in Series Parallel Circuits

Here's a video that explains the difference between series and parallel circuits, including the impacts of each on current and voltage.

Measure current through resistances in series-parallel circuits requires current-measuring skills used in both series and parallel circuits.

Measuring voltage drops across resistances in series-parallel circuits requires an understanding of both series and parallel circuit behavior. Learn more with this tutorial.

Use the formula for the parallel resistors to calculate the total resistance 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.

Use Ohm's Law to calculate the current in parallel circuits.

See how Ohm's Law can tell us that the voltage across resistors will depend on that current value I and each R-value.

When measuring the current in parallel circuits, compare the circuit's total current with the current through just one resistor.

Parallel circuits often provide less of a challenge for teens than parallel parking. An installment of a series on parallel electric circuits requires learners to solve increasingly difficult  levels of calculations. Each level...

Build an understanding of electrical circuits in series and parallel. The video instructor demonstrates the effects of manipulating both a series and parallel circuit. Learners realize the difference between the types of circuits as well...
