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 ...

Voltage is the electrical potential between two points. At one point of the voltage source, there is an abundance of electrons, and at the other point, there is a deficiency of electrons. This ...

Potential difference is measured in volts. The symbol for volts is V. For example, 230 V is a bigger potential difference than 12 V. Instead of talking about potential difference, people often ...

For clarity of purpose, I'll use voltage-feedback op amps in an inverting amplifier configuration as my circuit under test. This means that the input stage only has to reject the (hopefully small) ...

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 ...

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 ...

The total voltage drop is ~1.6 V. Therefore, if the current limiter is connected with a +5-V supply, the load will get ~3.4 V, which is unacceptable in low-voltage circuits.
