Philip Harris Resistance Unit

This practical resistance unit is ideal for teaching electricity and Ohm’s Law in science lessons. It enables students to explore how resistors behave in circuits, supporting hands-on learning and clear demonstration of theoretical principles.

• Includes 7 resistors: 1, 4.7, 10, 100, 1000, 10000, and 10000 Ohms

• Each resistor has dedicated 4mm red and black sockets for easy connections and can be connected in series or parallel to support investigation of the 'rules' for combining resistors.

• Resistors can be used in series or parallel arrangements

• All resistors rated at 0.25W

• Maximum current: 250mA (a.c. or d.c.)

• Dimensions: 160mm x 75mm x 31mm; Mass: 130g
