Voltage is the measure of the electric potential in an electric circuit to move an electric charge. It is measured in Volts; 1 Volt equals the potential needed to move 1 A of current against a 1 ohm of resistance. Two methods are generally used to convert Amps to Volts, theWatt’s Law...
Ohm’s Law– Ohm’s Law states that when electric current flows through a conductor (such as a cable), the intensity of the current (amps) equals the electromotive force (volts) driving it, divided by the resistance of the conductor. ...
That is calledrate. So, the formula V (volts) x A (amps)= W (watts) is similar to the car trip example. Both indicate rate. With the car, rate is equal to distance divided by time. Inelectrical systems, amperage and voltage are useful sets of information. But wattage is an addition...
the op-amp output swings positive, forward biasing D1 and developing an output across R2. Under this condition the voltage gain equals (R2+RD)/R1, where RDis the active resistance of this diode. Thus, when D1 is operating below its knee ...
