Delirium is not a static condition, it is one that undergoes shifts by the week, the day, or even the hour. A person who is suffering from delirium will usually find it difficult to focus on their usual daily tasks. Memories and emotions are affected, as well as the ability to think clearly and pay attention.
When describing voltage, current, and resistance, a common analogy is a water tank. In this analogy, charge is represented by the water amount, voltage is represented by the water pressure, and current is represented by the water flow. So for this analogy, remember: 1  Water = Charge. 2  Pressure = Voltage. 3  Flow = Current.
The voltage is measured between the two wires, and the current is measured in the wire supplying power to the load, often called the hot wire. Voltage can typically be measured directly by a Power Analyzer up to 1000 V RMS. Higher voltages will require the use of a VT (Voltage Transformer) on an AC system to step down the voltage to a level that can be measured by the instrument.
