Practical resistors can be made of various compounds and films, as well as resistance wire (wire made of a high-resistivity alloy, such as nickel-chrome). Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. The ratio of the voltage applied across a resistor’s terminals to the intensity of current in the circuit is called its resistance, and this can be assumed to be a constant (independent of the voltage) for ordinary resistors working within their ratings. Where I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and Ris the resistance of the conductor in units of ohms. This relationship is represented by Ohm’s law: The current through a resistor is in direct proportion to the voltage across the resistor’s terminals. We are going to design a “Resistor Code” App with Blackberry WebWorks SDK.Ī resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Blackberry WebWorks for Tablet OS as the name “WebWorks” implies, is a platform for building deeply integrated web applications for the Blackberry PlayBook. It is quite easy to design apps for Playbook, with recourse to Blackberry’s WebWorks SDK.
