For the circuit below, determine the resistor voltage. The source is 5 volts, the Zener potential is 5.2 volts and the resistor is 1k ohms.

Semiconductor components such as diodes and transistors are easily damaged by the high temperatures of soldering, so care must be taken to protect these components during the soldering process. One way to do this is to use a heat sink to draw heat away from the component without cooling the connection point too much. Heat sinks made out of sheet metal may be temporarily clipped to the component leads, one at a time, to prevent the solder's high temperature from thermally conducting all the way to the component body:   In the absence of a formal heat sink, can you think of any ways to fashion your own ïmpromptu" heat sinks out of commonly available tools and/or objects?

Could some please provide an explanation for VL why 15 and 1.33
