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.
Voltage is the pressure pushing on the electrons in a circuit. If all of the faucets in your house are closed, no water flows through the pipes. If you open one faucet, some water flows. If you open all of the faucets, a lot of water flows. This flow of water is similar to electrical Current.
