Should someone know the apparatus and the analysis of the experiment? WHy in other experiments it says "Measure"? For example "Measure the emf and internal resistance of a cell, e.g. a solar cell". Is it the same as "demonstrate"? Also, where can I find the ripple tank and current flow experiments? Thanks in advance?
