What are the compatibility options for Vivitar lenses with Nikon cameras?
Vivitar lenses are compatible with Nikon cameras that have a Nikon F-mount. This means that most Vivitar lenses can be used on Nikon DSLR and mirrorless cameras without any issues. However, it is always recommended to check the specific compatibility of the lens with your Nikon camera model before making a purchase.
What are the application of a thyristor?
The industrial applications of a thyristor are:To trigger a triacTo produce gate signalsto be used for controlled rectification
What does forced commutation mean?
The term "Forced commutation" is used when a thyristor is turned off using external components. If a thyristor is used in a DC circuit, when first turned on, it will stay on until the current goes to zero. To turn off the thyristor it is possible to use a Forced commutation circuit. The circuit creates a reverse voltage over the thyristor (and a small reverse current) for a short time, but long enough to turn off the thyristor. A simple circuit consist of a precharged capacitor and a switch (e.g. another thyristor) parallel to the thyristor. When the switch is closed, the current is supplied by the capacitor for a short while. This cause a reversed voltage over the thyristor, and the thyristor is turned off.
Can the Vivitar 728AF be used safely with the Canon Rebel xti?
Safely, yes, because it does not exceed 6V. Because the Vivitar 728AF is TTL-based and the Canon Rebel xti, being a digital body, is not TTL-compatible, but E-TTL, the Vivitar can only be used manually. It will fire, but there is no feedback from the camera to the flash unit. If you are willing to evaluate and reshoot every time, you can use this flash unit, but expect no more.
What is the importance of the Vivitar lens serial number and how can it be used to identify and authenticate a Vivitar lens?
The Vivitar lens serial number is important for identifying and authenticating a Vivitar lens. It serves as a unique identifier for each lens, helping to track its origin and manufacturing details. By cross-referencing the serial number with Vivitar's records or databases, one can verify the lens's authenticity and determine its production history. This information is crucial for buyers looking to ensure they are purchasing a genuine Vivitar lens.
How thyristor used in induction furnace?
Thyristor is used for Rectifiying and inverting the power supply in induction furnace. The parallel Resonance Coils (Current Control Furnaces) Control the Furance power up to 40% by controlling the firing angle of the rectifier inverter and remaining 60% controlled by inverter thyristor control. In rectifier they are varying the thyristor firing angle from 15 deg to 45 deg. (in sin wave)
What is the thyristor firing circuit?
The thyristor is basically used a switch in an AC circuit to control the amount of power fed to the load. To turn on this switch an "electric" pulse should be applied to the Gate terminal of the Thyristor. A circuit which supplies the "electric" pulse is called the firing circuit.
What circumstances led to the invention of the transistor in 1947?
before the invention of transistor,thyristor was used instead of transistor but thyristor produces more heat in the circuit and size is more when compared to transistor
What is the difference between thyristor fuse and normal fuse?
A: THYRISTOR can be used to clamp damaging energy as opposed to a fuse that must blow open and invariably takes time to blow. A thyristor is much faster and controllable actually if the problem disappear it can be made to open up again and restore power for normal operation.
Can Canon lenses be used on Nikon cameras?
No, Canon lenses cannot be used on Nikon cameras because they have different lens mounts and are not compatible with each other.
Can a Canon lens be used on a Nikon camera?
No, a Canon lens cannot be used on a Nikon camera because they have different lens mounts and are not compatible with each other.
Why sawtooth waveform is used in thyristor triggering circuit?
A sawtooth waveform is used in thyristor triggering circuits because it provides a linear and predictable voltage ramp, allowing for precise control over the timing of the thyristor's conduction. The waveform's rising edge can be synchronized with the zero-crossing of alternating current (AC), enabling accurate phase control in applications like dimming and motor speed control. Additionally, the sawtooth waveform facilitates the generation of a trigger pulse at a specific point in the AC cycle, ensuring reliable and consistent operation of the thyristor.
