On a company s balance sheet, a liability may be a legal debt or an accrual, which is an estimate of an obligation. Equity is the owner's value in an asset or group of assets.
A stable variable power supply with an adjustable output voltage from 5 volts to 30 volts can be
Variable Autotransformer. We can see that the variac can adjust the voltage to the load smoothly from zero to the rated supply voltage. If the supply voltage was tapped at some point along the primary winding, then potentially the output secondary voltage could be higher than the actual supply voltage.he section of winding designated as the primary part of the winding is connected to the AC power source with the secondary being part of this primary winding. An autotransformer can also be used to step the supply voltage up or down by reversing the connections.
