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 current gain and voltage gain?
Current gain is the ratio of output current divided by input current. Voltage gain is the ratio of output voltage divided by input voltage. Nothing more complicated than that.
What is wattage rating of microwave oven transformer also hi voltage from secondary?
The rating is about 1500W. This is for both the input and the output. Output voltage is usually 2,000 volts. Divide watts by input volts to get input current. And divide watts by output voltage to get output current. -Joe
Why is output dc higher than input ac?
Output power can never be more than input power. With a transformer, it is possible to increase the output current (while decreasing the output voltage), or to decrease the output current (while increasing the output voltage).
What will be input and output current of 10 KVA 3 phase UPS?
A 10 KVA 3-phase UPS will have an input and output current that depends on the specific voltage of the system. You can calculate the current by dividing the apparent power (in this case 10 KVA) by the square root of 3 multiplied by the voltage. For example, for a 208V system, the input and output current would be approximately 28.8 amps.
What is the meaning of voltage control device and current control device y they call like this?
In vcd, input voltage controls the output current.e.g.jfet In ccd , input current controls the output current. e.g. bjt
How a transistor work as an amplifier and as a switch?
"Transistor" name itself revels it transfers resistance from its input to its output (Transfer of resistance). Input resistance varies when input voltage varies, similarly output resistance varies and this leads to voltage variation at the output. Thus input to output voltage variation is called amplification. this is how transistor can be used as an amplifier. If input voltage is minimum output voltage becomes maximum i.e. its output resistance becomes maximum in common emitter configuration. Thus if no voltage is applied at the input its collector resistance becomes infinite or as if open circuit. Similarly if input current is increased output current increases and out put can behave as short circuit. This is how output current can be switched off or on using no input current or with minute input current. Unlike a digital device, the transistor is an analogue device which can be switch on/off to maximum or any gradient in between. Providing a small AC voltage to the base creates an amplified analogue of this signal across the emitter and collector.
Why input is voltage and output is current in fet?
The input is a Gate that is essentially infinite impedance, so no current. The output is essentially the resistance between Source and Drain, which controls the current flowing through it.
What is the input and output of a load cell?
The input of a load cell is the force or weight applied to it. The output of a load cell is an electrical signal, typically in the form of voltage or current, that is proportional to the applied force or weight.
How do rectifier circuits stabilize the output voltage when the input voltage is subject to fluctuations?
Rectifiers don't "stabilize the output voltage" of rectifier circuits when input voltage fluctuates. The rectifiers just rectify the input, and the output will fluctuate as the input does. Another form of "conditioning" of the rectified output is needed to address the issue of fluctuations. And we use the term regulation to talk about the effect of "stabilizing" an output voltage. Through regulation, the output will be resistant to changes in voltage when changes in the input voltage occur.
What is current series feedback?
The current series feedback is a negative feedback in which the output current feeds back a proportional voltage back to the input terminals in series with the input signal. Here the output impedance as well as the input impedance increases as both are connected in series.
What is buck boost converter?
Any device that outputs a voltage higher than its input voltage. This device can be capacitive, inductive, or other.
