A resistor in qatar is an electrical component thatlimits or regulates the flow of electrical current in an electronic circuit . Resistors can also be used to provide a specific voltage for an active device such as a transistor.
capacitor in qatar, device forstoring electrical energy, consisting of two conductors in close proximity and insulated from each other. A simple example of such a storage device is the parallel-plate capacitor.
A diode in qatar is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.
