The greater the potential difference or voltage, the greater the current flow.
In other words, when the potential difference between two points in a circuit increases, the current flowing through it increases. When the potential difference (v) between the points decrease, the current (I) decreases. In fact, the potential difference across a conductor is directly proportional to the current flowing through it when the tempterature of the conductor is kept constant.
V = I/R
Ohm’s law states that the current that passes through an ohmic conductoris directly proportional to the potential difference across it if the temperature and other physical condictions are constant.
An ohmic conductor is one which obeys Ohm’s law, while a conductor which does not obey Ohm’s law is known as non-ohmic conductor.
In Arabic, the word halal means permitted or lawful. foods are foods that are allowed under Islamic dietary guidelines. According to these guidelines gathered from the Qu'ran, Muslim followers cannot consume the following:
Organic light-emitting diode
An organic light emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compounds which emit light in response to an electric current. This layer of organic semiconductor material is situated between two electrodes. Generally, at least one of these electrodes is transparent.
OLEDs are used in television screens, computer monitors, small, portable system screens such as mobile phones and PDAs, watches, advertising, information and indication. OLEDs are also used in light sources for general space illumination and in large-area light-emitting elements. Due to their comparatively early stage of development, they typically emit less light per unit area than inorganic solid-state based LED point-light sources.
