In Figure 10, we can see that when voltage is stepped down from 240 V to 120 V in a 2 to 1 ratio, the current is increased from 1 to 2 amps, keeping the power equal on each side of the transformer. In contrast, in Figure 11, when the voltage is stepped up from 120 V to 240 V in a 1 to 2 ratio, the c ...

Stray voltage



Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
