| 1. | A common mnemonic is ACID for " anode current into device ".
|
| 2. | The ( copper ) anode current collector can dissolve into the electrolyte.
|
| 3. | In an IGCT, the gate turn-off current is greater than the anode current.
|
| 4. | A relatively small variation in voltage on the control grid causes a significantly large variation in anode current.
|
| 5. | Vacuum devices have a near constant anode current for a given level of illumination relative to anode voltage.
|
| 6. | It also results in higher transconductance, which is a measure of the anode current change versus grid voltage change.
|
| 7. | This involved use of a resistor from the cathode to ground, which provides better control of anode current through negative feedback.
|
| 8. | "In short the anode current is controlled by the electrical potential ( voltage ) of the first grid ."
|
| 9. | Although the capacitance is small, around 500 pF, due to the low anode current it is sufficient to act as a filter capacitor.
|
| 10. | The screen found in tetrodes and pentodes, greatly increases the valve's gain by reducing the effect of anode voltage on anode current.
