Problem Description A new electronic lamp (e-lamp) has been developed that uses a radio-frequency sinusoidal oscillator
Problem Description A new electronic lamp (e-lamp) has been developed that uses a radio-frequency sinusoidal oscillator and a coil to transmit energy to a surrounding cloud of mercury gas as shown in Figure la. The mercury gas emits ultraviolet light that is transmitted to the phosphor coating, which in turn, emits visible light. A circuit model of the e-lamp is shown in Figure 1b. The capacitance C and the resistance R are dependent on the lamp's spacing design and the type of phosphor. Design the value of R and C so that maximum power is delivered to R, which relates to the phosphor coating. The circuit operates at 0o = 107 rad/s. Analyze the circuit if the operating frequency is i) increased by ten times and ii) decreased by ten times. Phosphorus coating Mercury 100 Ω 1 μΗ vapor w Coil Coil Vo sinov R w C (b) (a)
