Resistors: Ohm's Law

Build a simple circuit and explore the effect of adding a resistor. Explore the relationship between voltage (V), current (I) and resistance (R). This learning object is one in a series of four objects. The series is also packaged as a combined learning object.

Resistors: series and parallel

Combine resistors in a range of ways to give new values of electric resistance. For example, connect them in series, or in parallel, or combine both. Predict the resistance of each combination. This learning object is one in a series of four objects. The series is also packaged as a combined learning object.

Resistors: voltage divider

Use resistors to divide the voltage from a battery. Arrange resistors to get small voltages from larger ones. Predict the voltage across any resistor in a circuit. This learning object is one in a series of four objects. The series is also packaged as a combined learning object.

Interactive Resource

Series circuits

In this resource, students will use a simulation to build a series circuit with batteries, light bulbs, resistors, and switches. From their experimentation, students will understand how different components affect the circuit, and explore the relationship between voltage, current, and resistance.
