pentode Sentence Examples
- The pentode tube features an additional grid, known as the suppressor grid, which enhances electron control.
- Pentodes are often used in high-power audio amplifiers due to their ability to handle large voltages and currents.
- The pentode's pentagrid structure allows for higher gain and improved linearity compared to triodes or tetrodes.
- Replacing tetrodes with pentodes in power amplifiers significantly reduces distortion and improves overall performance.
- Pentodes require a relatively high screen voltage to maintain proper operation, making them less efficient than triodes in low-power applications.
- The suppressor grid in a pentode effectively suppresses secondary emission from the plate, reducing noise and improving stability.
- Pentodes with multiple grids offer greater control over electron flow, enabling precise signal manipulation and amplification.
- The characteristic curve of a pentode exhibits a distinct flat region, known as the pentode region, which contributes to its high gain.
- Pentodes are commonly employed in power supplies, radio transmitters, and industrial control systems due to their robustness and high-power capabilities.
- The transition from vacuum tube pentodes to solid-state transistors marked a significant advancement in electronics technology.
