When pulse applied to op amp voltage goes from -3v to 9 in 0.6 s What is the slew rate of op amp?
The slew rate of an operational amplifier is defined as the maximum rate of change of the output voltage over time. In this case, the voltage changes from -3V to 9V, a total change of 12V, over a time span of 0.6 seconds. The slew rate can be calculated using the formula: [ \text{Slew Rate} = \frac{\Delta V}{\Delta t} = \frac{12V}{0.6s} = 20 , \text{V/s}. ] Therefore, the slew rate of the op-amp is 20 V/s.
What is the need for differential amplifier?
A differential amplifier will amplify the difference between 2 signals. This is useful in control systems, where one signal can represent what is actually happening (could be a position or speed, for example). The other signal can represent what is desired. A differential amplifier could be used in a cruise control on a car. When you set the cruise control, a voltage level can represent the speed that the car was traveling when set. If the car starts going up a hill and slows down, the voltage difference would be amplified, and the output of the differential amplifier can be sent to an actuator, which moves a lever to increase the rate of fuel going to the engine. When you get back to the desired speed, the difference is zero, and the actuator stops moving. If your speed increases too much, then it would have a negative voltage, so the actuator would move the other way, decreasing the rate of fuel to the engine.
What is ramp voltage?
Ramp voltage is a voltage that can be steadily increasing or decreasing.
How do you measure slew rate practically?
To measure the slew rate practically, you can use an oscilloscope to observe the output voltage of a circuit in response to a fast-changing input signal, typically a step function or a square wave. Measure the time it takes for the output voltage to change from a defined low level (e.g., 10% of the maximum voltage) to a defined high level (e.g., 90% of the maximum voltage). The slew rate is then calculated as the change in voltage divided by the change in time (V/Δt). This gives you the maximum rate of voltage change that the circuit can handle, typically expressed in volts per microsecond (V/μs).
What is rate of change of voltage?
The rate of change of voltage, often referred to as the voltage gradient, indicates how quickly the voltage across a circuit or component changes over time. It is mathematically expressed as the derivative of voltage with respect to time (dV/dt). This concept is crucial in understanding transient responses in electrical circuits, especially in applications involving capacitors and inductors. A rapid change in voltage can lead to issues such as voltage spikes or surges, potentially damaging sensitive electronic components.
How is slew rate affect on amplifier?
as it is rate of change of output voltage..so it affect amplifier output
What is slew rate?
slew rate is the ability of an amplifier to reproduce amplified version of the input signal in terms of frequency and phase. The input signal amplitude change is fast. But the amplifier will take some time to give response to the changes in input signal. i.e. how fast the amplifier tracks the input signal is the slew rate. For an amplifier the slew rate should be high in order to avoid signal distortion. The rate of change of the output voltage of an amplifier for the given input signal change is called the slew rate.
Why roller follower is preferred to that of knife edge follower?
There is a rapid rate at which the knife-edge wears. Therefore roller follower is preferred to knife-edged follower because there is almost no wear because in case of roller follower the relative motion is rolling and not of sliding type

How is different between voltage and current?
voltage = the electrical "pressure"current = the electrical "movement rate" or "flow rate"

What is horizontal and vertical amplifier in cathode ray oscilloscope?
The horizontal and vertical amplifier in the cathode-ray oscilloscope are deflection plates. The horizontal amplifier causes the beam to be deflected horizontally at a rate that is uniform. The vertical amplifier causes the beam to deflect vertically.
What is ramp voltage?
Ramp voltage is a voltage that can be steadily increasing or decreasing.
How choose voltage according to power?
how to choose rate of voltage according to power
What is edge speed in electronics?
A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line. A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line.
What is the allowable capacitance and voltage difference when replacing a capacitor?
I depends on the application for a rate amplifier the exact value is mandatory but for filtering that can vary greatly since every cap of that type has a very large -/+ tolerance YOU may install a greater voltage breakdown but never a less then the original
How does voltage affects the amount of energy that is transformed?
Voltage determines the rate at which energy is transferred in an electrical circuit. Higher voltage results in a faster rate of energy transfer, which can lead to more energy being transformed in a given period of time.
