Steady Current And Current Density


https://www.electronics-lab.com/article/steady-current-and-current-density/

Introduction Many practical applications and devices are based on the principles of static electricity. However, electricity was destined to become an inseparable part of our daily lives when scientists learned how to produce a continuous flow of charge for relatively long periods using batteries. The battery, or voltaic cell, was invented in 1800 by Italian […]

Dual Channel Voltage-to-Current (V-I) converter circuit with BJT


https://www.electronics-lab.com/project/dual-channel-voltage-to-current-v-i-converter-circuit-with-bjt/

This low-side voltage-to-current (V-I) converter delivers a well-regulated current to a load. The circuit accepts an input voltage from 0V to 3V and converts it to a current from 0A to 6A (combined). The current is accurately regulated by feeding back the voltage drop across a low-side current-sense resistor (R8, R9 + R16, R17) to […]
