Description | By connecting an ac power source to one of the coils and reading the voltage from the other coil transformer action (either step up or step down) may be readily demonstrated. The efficiency of the transformer may be studied –does the efficiency change if the laminate top is not firmly fixed? What happens if it is not present? Other more esoteric effects such as Magnetostriction may also be studied. |
A very popular and compact Westminster power supply that is ideal for school use in Key stage 4 and 5 physics lessons with its tough steel case protected by a tough powder coated finish that will last years of use. The unit will deliver up to 16A AC or DC through its colour coded terminal posts. This power supply is very popular for use in electromagnet experiments.

Class set of 15 Capacitance Substitution Boxes. The IPC Capacitance Substitution Box (IPC-5861-X) provides the easily selection of 12 preferred value capacitors, ranging from 100pF to 0.47µF.
The values range from: 100pF, 220pF, 470pF, 1nF, 2n2, 4n7, 10nF, 22nF, 47nF, 0.1µF, 0.22µF and 0.47µF. All the capacitors offer a maximum voltage rating of 50V (AC or DC), with actual capacitance value tolerances of ±5% to ±10%. The unit is housed in a robust ABS plastic case with rotary selector switch and a pair of 4mm connection sockets.

The Powerbase V8 comes with a high power rotary transformer and a high specification toroid transformer replaces the original chassis transformer. The unit supplies 0-20V smoothed dc and 0-16V AC at 8 amps. The output is continuously variable and protected by a panel mounted thermal cut out. An output limiter is fitted which allows the user to preset the maximum voltage available. |
