Introduction: The purpose of this experiment was to teach the students about DC circuits. Topics in DC circuits to be looked at are current, voltage drop, capacitance, resistance, Ohm’s law, diodes, conductivity. Theory: We began by examine currents against voltages to get resistances, using a graph to find out the resistance, because the slope of the current against voltage line will be 1/R. This is done to validate Ohm’s law, the equation I=V/R . I is of course current here and V is voltage, R was to be found using the reciprocal of the graph, meaning the smaller R is,

Unformatted text preview: the more vertical the line will be. Next we looked at diodes and studied their properties. Zener diode behavior should allow that in one direction if a current above .4 to .7 volts is exceeded, there is almost no resistance. Silicon diodes should show that Light emitting diodes were to be measured and calculated. The amount of power used by the LED can be found by the equation P=IV, but the numbers we have are not necessarily accurate for the LEDs we are actually using numbers that aren’t necessarily specific to this LED. We are also calculating We progressed on to looking at heat on resistors, such as an incandescent light bulb,...
