What Is an Amp? Amperage measures the rate that current flows through an electrical circuit. If voltage is like water pressure, amperage is like the rate of water flow.

A multimeter is a powerful tool for measuring electrical values such as voltage, resistance, and current, commonly used in ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with ...

This difference causes the electrons to flow within a circuit and its load. The greater the difference (voltage), the greater the force (pressure) that is required to push or pull of electrons through ...

Learn how to measure current and voltage and the advantages of parallel circuits.

Part 3 examines how a varying power supply voltage effects the output of a basic op amp circuit. Part 4 offers a cautionary tale on using op amp macromodels – what you see in your simulation is ...

Most modern operational amplifiers (op amps) operate over a 5-V (or ±2.5 V) or lower voltage range. For applications requiring a larger input-voltage swing, such as industrial circuits, suitable ...

A potential difference close potential differenceThe potential difference (or voltage) of a supply is a measure of the energy given to the charge carriers in a circuit. Units = volts (V). This is ...

Most older and a few current IC op amps have a separate null or trim pin input to which a corrective voltage can be applied. Another solution is to add a resistor in the non-inverting input, which ...

The potential difference, or voltage, between the plates is proportional to the difference in the amount of the charge on the plates.
