Variable Dummy Load for Power Supply Testing

Leave a comment

Figure 1. Assembled Variable Dummy Load To test real capacity of a power supply, we need a load with variable current consumption. If we have high power variable resistor such as tapped wire-wound resistor, we can directly connect this resistor and make some measurement. Unfortunately, this kind of high power resistor is expensive and not so flexible getting wide adjustment […]

Direct Reading Inductance Meter Employs Triangle Wave Generator

Leave a comment

Figure 1.  Assembled Hamuro Inductance Meter Circuit Inductance and The Measurement Unit Inductance is a property of electric conductor, and it expresses the characteristic of generating electromotive force or voltage when the amount electric current changes inside it. It looks like a concept of inertia of mass in the mechanical domain when it generate force if the speed of its […]
