While trying to find the rating of your toaster you find the circuit diagram instead. Your friend believes there must be an error in the diagram. The heating element responsible for toasting is listed as having a resistance of 4 ohms. A variable resistor, which is changed by a control knob, has a range of from 3 to 25 ohms. Your friend feels this resistance will not toast bread properly. Based on the diagram below, you decide to calculate the maximum power output by the heating element.

6. LED Alarm Circuit One day, you come back to your dorm to find that your favorite candy has been stolen. Determined to catch the perpetrator red-handed, you decide to put the candy inside a kitchen drawer. Using the following circuit design, you would like to turn on a light-emitting diode (LED) "alarm" if the kitchen drawer is opened. Rli LED 2.5V LED Note Rphoto is a photoresistor, which acts like a typical resistor but changes resistance based on the...
MATLAB MATLAB MATLAB Consider the diagram below V R$ Here, each V represents a change in voltage (in volts) at a battery, each R represents a resistance in ohms) at a resistor and each I represents a current (in amps) through a wire. These quantities obey two simple laws: 1. Ohm's law: The voltage drop across a resistor is V = IR. 2. Kirchhoff's second law: The sum of all the voltage changes in a closed loop is zero. Using...
Notes for lab dc02-Resistors and the Color Code will skip are Part 2 e, g: Part 4; Exercises 2, 4,5,6 and 3. It is important to answer the exercises correctly in each labl you should include the appropriate prefix for the unit in the Numerical Value We will not be Volt using the Volt-Ohm meter (VOM) for this lab, so skip the parts that ask for VOM measurements. The parts we You do need to complete Exercises1 Note that in...
