The voltage across the ends of the cell is called the terminal potential difference, \(V_{tpd}\). \(V_{tpd}\) can also be calculated as \(I R\) where \(R\) is the load resistance. Voltage is a measure ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

This circuit is designed to check the condition of lead-acid and gel cell batteries with capacities greater than 20Ah. It switches a load of about 18A at a rate close to 50Hz so that the internal ...

Occasionally, we find fun new electronic instruments in the wild and can’t resist sharing them with our readers. The item in question is the FNIRSI HRM-10 Internal resistance meter, which we show here ...
