You need to know how to investigate how current changes with voltage for a component, eg for a resistor (or wire) at constant temperature, a filament lamp and a diode. You should be familiar with the ...

The resistance formula, R = V/I, shows how voltage and current determine opposition in a circuit. Central to Ohm’s Law, it is widely applied in electronics, power distribution, and engineering to ...

A parallel circuit is one of the fundamental electrical circuits wherein various components, such as resistors, are arranged with their heads connected together, and their tails connected together.

When working with electrical circuits, one of the most fundamental concepts to understand is how to calculate the voltage drop across a resistor. Voltage drop refers to the decrease in voltage as it ...

To investigate experimentally how the resistance of a metallic conductor at constant temperature depends on length and obtain sufficient values to plot a graph of resistance (y-axis) and length ...

I will use an SQLite database for the authentication and will use Tkinter for the GUI. Depth-First Search will be utilised to find neighbouring nodes to identify whether the circuit is series, ...
