Growing concerns about energy efficiency have led to the development of electronics with higher power density. In grid-connected and industrial applications, such as AC motor control, uninterruptible ...

Engineers could avoid expensive redesigns by planning medical device testing early in development with expert guidance.

Leakage current is one of the most stringent, yet telling, parameters of possible danger to patients or caregivers. It does not take much electric current flowing through the human body to cause harm.

Manufacturers of medical electrical equipment are required to test to the international electrical safety standard IEC 60601 Medical Electrical Equipment, General Requirements for Safety, to ensure ...

Residual current circuit breakers (RCCB) play a narrow but important role in electrical protection. They are frequently specified, often misunderstood, and regularly credited with capabilities they ...

Each year in the United States, there are thousands of incidents of utility poles catching fire and causing damage. Crossarms break. Equipment falls to the ground. Sometimes the entire pole catches ...

Figure 1. Use the circuit in (a) to measure input bias current on the op amp’s noninverting input. Adding a loop amplifier in (b) keeps the op-amp stable for measurements on the inverting input. The ...
