This circuit provides different ways to measure the current-voltage phase displacement of a line-powered ac load. The classic approach for sensing an ac load's current requires a transformer or ...

The process of water–gas displacement in water–drive gas reservoirs has been always an important research topic. However, knowledge about the flow patterns of water–gas flow under different conditions ...

In a power-supply topology for a computer system with a 12-V input and a 1-V, 20-A output, currents are high enough that duplicate power stages can be used to reduce stress and spread the thermal ...

In operational amplifier stability, one rule of thumb is to allow 45 degrees of phase margin. Other design guidelines state that 60 degrees is best; still others say that 30 degrees is sufficient.
