Windows Phone 8.1 arrived last year, finally bringing many features lacking from Microsoft's platform. Now, Microsoft is on the verge of rebooting once again with Windows 10 Mobile. Windows Phone has been rebooted enough. With constant Windows Phone change, the only thing that has remained persistent is a lack of apps.
Part of the Electronics glossary: The dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space. It is an expression of the extent to which a material concentrates electric flux, and is the electrical equivalent of relative magnetic permeability.
Constantan is a Nickel-Copper based alloy wire that has a high resistivity and is mainly used for thermocouples and electrical resistance heating. It has a constant resistivity over aa wide range of temperature.onstantan Wire Resistance. The resistance of constantan wire is 15.94 ohm-cmil/ft. Since the resistance of constantan does not change with temperature, it is used for the purpose of making thermocouples and other such appliances where the resistance should remain constant for a particular range of temperature.
