Ratio or amplifier output signal to its input?
It never referred as ratio but Rather a gain A in the form of output divided by the input and implies voltage A=gain. basically is input resistance divided by the feedback resistance
Is the ratio of output force to input force of a hydraulic press equal to the ratio of the output and input piston areas?
Yes, the ratio of output force to input force of a hydraulic press is equal to the ratio of the output and input piston areas. This relationship is based on Pascal's principle, which states that pressure applied to a confined fluid is transmitted undiminished in every direction.
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.
How do you find speed ratio?
The speed ratio is typically calculated by dividing the speed of the input gear by the speed of the output gear in a gear system. This helps determine how much the output gear rotates in relation to the input gear in a given amount of time.
What is the input to output ratio formula?
output/input
What is the Speed ratio formula?
The speed ratio formula is the ratio of the speed of the output gear to the speed of the input gear in a gear system. It is calculated as the number of teeth on the input gear divided by the number of teeth on the output gear.
Efficiency is usually expressed as a what?
Efficiency is usually expressed as a ratio of output to input, such as output divided by input. It measures the effectiveness of achieving desired results with minimal waste of resources.
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.
Is a machines mechanical advantage the output force multiplied by the input force?
No, a machine's mechanical advantage is the ratio of the output force to the input force. It indicates how much a machine multiplies the input force to produce the output force. The formula for mechanical advantage is output force divided by input force.
What is the ratio of output to input?
efficiency
What is the mechanical advantage of a machine that requires n of input force to produce 15 n of output force?
The mechanical advantage is the ratio of the output force to the input force. MA = output/input (output force divided by the input force) For the example, 15N/30N gives the MA as 0.5 (one half).
The efficiency of a real machine?
Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of the machine.
