next time, we are gonna built power supply.
Understanding magnetic field goes is important which generates current to wire. when we connect to he capacitor, it has limits to accept the current. we cannot get exact measurement to charge capacitor as we cannot take account the resistance of wires. with current, strong magnetic field generates.
T = RC
when coil generates voltage, the
when we disconnect power source,
when we disconnect arduino from a circuit, back voltage happens which kills transistor, potentially.
Semi conductor: Diode
If we have coil, when we energize the coil, snubing
it’s important to know how diode behave when we switch off the power source
battery is a chemical substance. As we use the battery, we use ions. No ions available, we cannot use the battery never again. battery loses the capacity if we charge half way.
Good battery made by gel, otherwise discharges chemical substance
- makes DC magnet field, transforming energy one coil to another coil
sign wave, coil changing change magnetic property
no square wave in nature. we generate square wave by adding sine waves
capacitor charge or discharge caused by signal
check frequency and capacitor:
lower frequency higher capacitor
capacitors, and conductors based on this formula:
square wave has lots sine waves
capacitor, waves, coil,
practice by using electronic tool box
