The RC circuit

Posted by organtin Mar 4, 2016
This time I am going to share with you an amazingly simple experience that is made possible using just an Arduino UNO board, a resistor and a capacitor. The RC circuit is a classic circuit in physics teaching and is composed by just a resistor R and a capacitor C in series. For details you can look at the Charging a Capacitor page of the HyperPhysics pages. Pupils study the charging and discharging of the capacitor when the circuit is connected to a battery. A rather simple mathematics gives the ...
