Given vacuum tube constants, what grid bias voltage is obtained when Gp = 1000 V and Ig = 10 mA?

• A. 25 V
• B. 50 V
• C. 100 V
• D. 75 V

Answer: (B)

To determine the grid bias voltage in a vacuum tube using the given constants of Gp (the grid-to-plate voltage) and Ig (the grid current), you can apply the relationship derived from the basic principles of vacuum tube operation. First, the relationship between the grid bias voltage (Vg), plate voltage (Vp), grid current (Ig), and the transconductance (Gp) is utilized. Grids in vacuum tubes operate by controlling the flow of current between the cathode and the plate. When a certain grid voltage is applied, it influences the amount of current that can pass through. In this case, we are given that Gp is 1000 volts and Ig is 10 mA. The grid bias voltage (Vg) can be calculated using the formula that incorporates these variables: Vg = (Gp) - (Ig * Rg) However, since we do not have a specific value for Rg, we can rely on the fundamental understanding that when Gp increases, the grid bias must effectively balance the current flowing through the grid. Given that this specific configuration leads us to predetermined values in practical applications or standardized calculations, we can align the desired bias point empirically or through common tabulated values relevant to typical
