Circuiti Elettrici Alexander Sadiku Pdf 11 Repack

First, he determined the specifications of the LED: it required 2V and 15mA to operate correctly. With a 9V battery as the power source, Alex calculated the required resistance to drop the voltage from 9V to 2V while limiting the current to 15mA.

The task at hand was to design a simple circuit for a LED indicator that would be used in a safety device. The goal was to ensure that the LED received the correct voltage and current to operate efficiently without burning out. Alex had been struggling to balance the theoretical knowledge from his textbook with the practical application. circuiti elettrici alexander sadiku pdf 11 repack

Excited by his progress, Alex decided to select a resistor with a value of (470\Omega), a standard value close to his calculation. He then simulated the circuit using a software tool before building it on a breadboard. First, he determined the specifications of the LED:
