Students will apply Ohm’s Law. Students will use a multimeter to measure current, voltage, and resistance. Students will use a breadboard to set up a series circuit. Students will read circuit diagrams. Students will calculate times for an RC circuit to change state. Students will prove that resistors in series have an equivalent resistance equal to their individual sums. Students will program the Basic Stamp to measure voltage levels in a voltage divider and RC circuit.
In this lesson students will be introduced to series circuits, resistors, a photoresistor and a microcontroller. There’s a lot here, but it boils down to making a voltage divider circuit and measuring the voltage at different points. A second circuit includes an RC component. Teachers can edit this down to just a photoresistor if time and/or... View full description >>
