Concord Consortium: Calculating Current in Parallel Circuits

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

Use resistance formulas to determine the total resistances of the series and parallel parts. Then, use Ohm's Law to calculate the voltage drops across and currents through each part.

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

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

Measuring the voltage in a circuit is like measuring the drop in pressure across two points. Learn more with this tutorial.

See how oscillations in an AC circuit don't always rise and fall together.

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...
