An electric circuit kit holds everything needed to build a working circuit: wire, bulbs and holders, knife switches, resistors, cells and leads. You can buy the kit or just the part that went missing, which matters when it is the third set of crocodile leads this term.
Suits CAPS circuits work from primary right through to FET phase. Running the Ohm's Law practical? Our Grade 11 Ohm's Law guide walks through the method, the graphs and the free marking memo. Building circuits with Grade 9? The series and parallel circuits guide covers both layouts and what happens to current and voltage in each. Starting out in Grade 8? The electric circuits practical covers the components, how to draw a circuit diagram that earns its marks, and the heating, magnetic and chemical effects of a current.
Grade 7 meets energy before it meets circuits, and a few of these parts are all it needs. The potential and kinetic energy practical uses a cell, a bulb and two leads to trace an energy conversion from chemical through to light and heat, and it replaces two activities that are unsafe as they are usually printed: a sealed tin heated over a burner, and a rubber band fired across a classroom.
