Concord Consortium: Measuring Current in Parallel Circuits

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

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.

Find out how measuring current in a circuit is like measuring the flow rate of water in a sprinkler system.

There are three different measures of AC voltage. Here, consider the peak voltage to measure it.

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

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...

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.
