Stringing of cells in a PV panel Draw the tabbing and bus-bar wires for a 72 cell module using three substrings and a junction box mounted in the typical central location. Each substring is protected by a bypass diode. No precision drawing is needed (i.e. you don't need to draw every single cell, the main arrangement of substring and how you connect to the jnction-box is relevant.
The channel resistance of a MOSFET can be computed by getting the reciprocal of the derivative of the drain current with respect to the drain to source voltage. Compute the channel resistance (in Q) of an NMOS operating in the linear region given the following MOSFET specifications: k = 3.77µA/V2, wIL = 125, VGS = 3V, VTH = 0.76V, and Vps = 0.64V.
