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.
When a voltage is applied to the conductor, the free electrons all flow in the same direction, which is called a current. While electrical energy is transferred through the conductor at nearly the speed of light, the individual electrons move at a much slower pace.
