Students will learn the difference between Emf and Voltage (i.e. ideal voltage and the output voltage) and how to calculate the internal resistance of a battery.
Internal resistance of a battery is demonstrated, explained, and calculated.
Every battery has some internal resistance; in this quiz students calculate that internal resistance as a small resistor in series, and the voltage drop associated with it.
A list of student-submitted discussion questions for Internal Resistance.
This study guide is an overview of circuits and circuit diagrams. It discusses voltage, current, Ohm's law, loop rule, and junction rule and reviews how to solve resistors in series, resistors in parallel, capacitors in series, and capacitors in parallel.
