Originally, current was defined as the flow of charge from positive to negative. Scientists later discovered that current is actually the flow of electrons, from negative to positive. The original ...

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.

ROHM’s ultra-compact CMOS Operational Amplifier (op amp) TLR1901GXZ achieves the industry’s lowest operating circuit current.

Follow the current Remember that we call a collection of connected electrical or electronic components a “circuit” because currents always flow from a source to a load and then back via a return ...

We talk about electrical current — just like current in a stream. Many introductory books on electricity try to relate voltage to water pressure, electric current to water flow, and resistance ...

Conventional current takes just the opposite direction, from the positive terminal, around the circuit and back to the negative terminal.

If the loop is broken at all, it becomes an open circuit, and no current will flow. In this project you will build your own simple circuit by disassembling a flashlight (with permission, of course).

Despite their designed current-handling capacity, such circuits still need current limiters and circuit breakers to protect them from fault conditions.
