RC Lab – rolinychupetin

This is an interesting (if not too formal) lab.  Roly shows how to layout the lab on a breadboard (it’s very neat! maybe even obsessively neat) and measure the duration of one time constant on a digital oscilloscope. No audio… pity, this guy looks and sounds like Sean Connery.  Roly is a PhD in Electrical Engineering and teaches at the University of British Columbia, Vancouver.  Compared to his method, there is nothing wrong with going top to bottom of the FULL charging cycle and then applying 5 time constants to the  duration and dividing by 5.  BUT if you do not have the entire 5 time constant rise of the circuit, then the method here is the best.
