What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
What determines the output voltage and the current of a transformer?
The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.
What is the relationship between output voltage and duty cycle in a step down chopper?
If you have a cigar lighter to USB power converter used in your automobile to charge from a USB bus that fits in your car cigar lighter, the USB voltage is 5V. The car is 12V. So there is a switch to turn it on for 5 ticks and off for 7 ticks 42% duty cycle if you wanted 1.2V 10% duty cycle
Why might the unloaded output voltage of a transformer be higher than its rms of 12.6v?
Because the windings of transformers have resistance, the primary and secondary currents will cause voltage drops. To compensate for the drops, the transformer may have been designed to have a higher than specified output voltage when there is little or no output current. The no load output voltage typically is only slightly greater than the specified voltage. Before measuring the output voltage, measure the input (line) voltage. If it is not as specified for the transformer, calculate its effect on the output.
How do you connect Two DC generators together to double the output voltage?
You would connect them in series to double the output voltage.
Is there any way to control the voltage output on usb?
The output voltage available at a USB port is controlled by the regulator in the computers power supply. It is fixed, you can not change or control it. The maximum current which should be drawn from a USB2 port is 500mA, from a USB3 port it can (I believe) be up to 850mA.
Is a USB Port input or output?
A USB port is both an input and an output.
Is a USB cable an input or output device?
A usb cable is not a device. A USB drive would be a Storage Device and still not be an Input or Output device. A USB keyboard would be an input device and a USB printer would be an output device.
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
How do you cenvert usb output into network cable output?
You can buy USB network card, it will solve your problem.
Is a cable an input or output device?
A usb cable is not a device. A USB drive would be a Storage Device and still not be an Input or Output device. A USB keyboard would be an input device and a USB printer would be an output device.
Is it the value of input voltage equal the value of output voltage?
No. There are several factors that may affect the output voltage. For instance: Resistors, Transformer, Voltage regulators and others that can control the output voltage to a certain level.
What is usb bus power?
The Voltage at which the USB Drive works at.
Is USB drive input or output?
It's an output. I think. The usb port is already in there, so it should be an output. An input is something you put in, and an output is something that comes out. Hope this helps. :)
How does an alternator know how much voltage output?
Output of the alternator is controlled by the voltage regulator.
How can be a DC voltage source output voltage made half of its output voltgae?
By using something called a voltage divider.
What determines the output voltage and the current of a transformer?
The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.
