AC Filtering With Capacitors
Students investigate the properties of capacitors and discover that capacitors block DC and filter AC. They discover the function of capacitors. Students differentiate between AC and DC power. They explore the role of resistors.

Construction of an Ammeter and a Voltmeter from a Galvanometer
Students explore series and parallel circuits. In this physics lesson, students construct a simple circuit and measure its maximum current. They construct their own voltmeter and ammeter that operates at a specified range.

OHM's Law
Students study the relationship between current, voltage and resistance in a series circuit. In this investigative lesson students watch a demonstration and see how voltage is measured and see what OHM's law is.

How a Circuit Works
Young scholars discover the basic principles of circuits by designing and testing some of their own. They are told that circuits usually have a power source such as a battery and a resistor such as a light. Students make a circuit using...

Maximum Power Point
Students investigate how to optimize the power output of a photovoltaic cell using a home-made gnomon stand. They use data collected to create current-voltage and power-voltage curves to determine the "maximum PowerPoint," (MPP) at which...
