The volt-ampere characteristic is a graph of the current flowing through the device versus the electrical voltage connected to the device. It is only the basic shape of the characteristic and the general course of the current and voltage dependence that tells us much about the electrical element.
A Photocell is basically a resistor that changes its resistive value (in ohms) depending on how much light is shining onto the squiggly face. They are very low cost, easy to get in many sizes and specifications, but are very inaccurate. Each photocell sensor will act a little differently than the other, even if they are from the same batch.
Determination of Planck''s Constant Using the Photoelectric E
A Leybold photocell served as our target, containing a potassium (W0 = 2.3eV) photosurface as the cathode and a platinum ring (Wa = 5.7eV) as the anode sepa-rated by a vacuum. It was enclosed in a black box with a small circular opening to allow for incoming light. Pre-cautions were taken to shield the setup from ambient
