Wheatstone Bridge, A1-1020.00, £23.50
 The only additional component required to operate the Wheatstone Bridge is a Decade Resistance Unit.
The teacher can put their own values of resistor into the circuit using the easy access screw terminals. If there are several boards in the classroom then the pupils can verify the relationship for several different conditions.
The board strips away the complexity of wiring the circuit and brings the Physics to the forefront.
The very important relationship between the out of balance resistance and current can easily be studied.
Wheatstone Bridge connected to the djb microtech's decade resistance board.
Typical results.
