Pack of 10 12V 21W Small Bayonet Cap (SBC) Radial Filament Lamps.
| Other equipment needed is two standard 4mm plugged leads and a power supply capable of delivering 2-3 volts at 1 amp. | Code: ELB8000
Students often think that the brightness of a lamp is only dependent on the current flowing through it. The unit allows the teacher to safely switch a 12V lamp in series with a mains lamp and study the current flow through them.

Our mini national grid system is a very cost-effective way of teaching the principles used by the National Grid to supply electrical power to our homes. This kit comprises two printed circuit boards and a set of "HT" leads to interconnect them and is SELV (Safety /Separated Extra Low-Voltage) classed, which means that no part of the system is at more than 50 volts - which means it is very safe and suitable for student use. The system allows the user to compare electrical transmission at low and high voltages and the results are displayed by the brightness of the two on-board MES lamps which are supplied.
| This includes kit includes the use of a safety mains lamp socket, which has a built in a switching system that only allows it to be switched on when a lamp is inserted. We have also included two switches, which must be pressed simultaneously to route the mains current through the low voltage lamp. Furthermore, the switches are sited at opposite ends of the case, requiring two hands to operate them. However, it must be appreciated that you are working with potentially lethal voltages and currents and therefore extra care should be taken.
