Learn how engineers design electrical circuits by calculating the voltage, current and resistance of electrical components.

The most common circuits for current determination are given in Figure 2. A sense resistor is connected in series with the supply line carrying the desired current.

Learn how electric circuits work and how to measure current and potential difference with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

If you're seeking a way to measure current and power in a circuit, you need to know about current-sense amplifiers (CSAs). A CSA is a specialized op amp connected as differential amplifier with ...
