ENG EK 131 Study Guide - Quiz Guide: Autodesk, Led Circuit, Voltage Divider
Document Summary
Over the past 2 weeks, we have learned about circuits wiring, ohm"s law, kvl, kcl, p-n junction (diode) and leds. Based on what you learned, answer the following questions: the circuit below shows a voltage divider. Solve for the following values from this circuit: the current through both resistors, i in terms of v, r1 and r2, the equivalent resistance of the circuit, req, and the voltage drop across both resistors, v1 and v2. Assume the following values for the circuit v = 9 volts; r1 = 500 ; r2 = 1 k : for the led circuit that you have built in class in weeks 6 and 7, you have powered the circuit using 9v battery. You have used 470 or 560 ohms resistor. Tinkercad using 1000 and 220 ohms resistors, respectively. What happens to the brightness of the led.
