There is now a safe way to demonstrate step up/down voltages. Adjust the size of the voltage. Demonstrate easily and safely why power companies step up/down the voltage when transmitting electricity over large distances. Voltage can be stepped up or down in a voltage ratio of 0x, 8x 12x, and 16x. Observe the change in brightness of the Consumer lamp as you do so.

Measure power losses within the transmission lines

Fully self contained unit. Use your multimeter to measure step up/down voltage and currents

Compact unit (37cm long) for easy storage.
