It depends on the shunt feedback resistor on the op-amp, for example with a 10k feedback resistor connecting the output to the inverting input, 1 mA input current gives 10 volts signal output. The input terminal stays near zero voltage because of the high open-loop gain of the op-amp, so the inverting input is termed a 'virtual earth'.

Which AC input transformer required for 5volt dc output power supply?
It depends on the required output current, load rejection factor, and ripple. Also, efficiency enters into the picture.
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 offset null in lm741?
When using the LM741, one of the inputs will have a bias (usually non-inverting input), which means the output can never be 0 V. If a 0 V output is needed, you need to offset the bias. To do this, you can connect both inputs to two 1K resistors in parallel, or both inputs to either side of a 10K potentiometer. This will allow an output of 0 V from the opamp.
What is the input current for common collector?
from the name itself the common collector has its collector terminal in common with both the input and output circuits of a transistor and the base current is chosen as the input current and the output current is the emitter current
How do you check a transformer for ac house unit?
Check that the input and output voltages are as required. Check that the transformer is big enough for the current required for the unit you have.
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 required input and output voltages for a personal computer to power on?

A mealy state machine output depends on?
A mealy state machine output depends on both the current state and the input signal received. The combination of the current state and the input signal dictates what the output of the machine will be for a given transition.
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 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.
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.
