It is essential to become well-versed in the use of an oscilloscope for displaying voltages. If you have access to more than...
Class practical: an introduction to the concept of internal resistance, using a more interesting example than a battery.
Class practical: finding an internal resistance of a supply from the power dissipated by a load resistance.
This activity introduces the internal resistance of a cell. You can easily point out the distance that the charged particles...
The batteries commonly used in school science practical work are torch batteries rated at 1.5 volt . If two of these batteries...
The starting point for the theory can be either Kirchhoff’s second law or conservation of energy in the circuit (the same...
