In this simulation you will investigate relationships between voltage, resistance, and current that exists in an electric circuit. You will adjust voltage of the power source and resistance of the resistor and then use digital multimeter to obtain measurements. Then you will record these measurements and look for relationships that exist between voltage, resistance, and current.
Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change.

" The course, which spans two thirds of a semester, provides students with a research-inspired laboratory experience that introduces standard biochemical techniques in the context of investigating a current and exciting research topic, acquired resistance to the cancer drug Gleevec. Techniques include protein expression, purification, and gel analysis, PCR, site-directed mutagenesis, kinase activity assays, and protein structure viewing. This class is part of the new laboratory curriculum in the MIT Department of Chemistry. Undergraduate Research-Inspired Experimental Chemistry Alternatives (URIECA) introduces students to cutting edge research topics in a modular format. Acknowledgments Development of this course was funded through an HHMI Professors grant to Professor Catherine L. Drennan."
This new version of the CCK adds capacitors, inductors and AC voltage sources to your toolbox! Now you can graph the current and voltage as a function of time.

In the everyday electrical devices we use calculators, remote controls and cell phones a voltage source such as a battery is required to close the circuit and operate the device. In this hands-on activity, students use a battery, wires, small light bulb and a light bulb holder to learn the difference between an open circuit and a closed circuit, and understand that electric current only occurs in a closed circuit.

Students investigate circuits and their components by building a basic thermostat. They learn why key parts are necessary for the circuit to function, and alter the circuit to optimize the thermostat temperature range. They also gain an awareness of how electrical engineers design circuits for the countless electronic products in our world.

This module will introduce you to many of the basic concepts involved with Electricity and Magnetism. We will introduce you to static charge, moving charge, voltage, resistance, and current. We will learn about the properties of magnets and how magnets are used to produce electric current.
Students learn about current electricity and necessary conditions for the existence of an electric current. Students construct a simple electric circuit and a galvanic cell to help them understand voltage, current and resistance.

Students are introduced to the idea of electrical energy. They learn about the relationships between charge, voltage, current and resistance. They discover that electrical energy is the form of energy that powers most of their household appliances and toys. In the associated activities, students learn how a circuit works and test materials to see if they conduct electricity. Building upon a general understanding of electrical energy, they design their own potato power experiment. In two literacy activities, students learn about the electrical power grid and blackouts.

Students learn about the underlying engineering principals in the inner workings of a simple household object -- the faucet. Students use the basic concepts of simple machines, force and fluid flow to describe the path of water through a simple faucet. Lastly, they translate this knowledge into thinking about how different designs of faucets also use these same concepts.

This course explores fundamental questions about the causes and nature of revolutions. How do people overthrow their rulers? How do they establish new governments? Do radical upheavals require bloodshed, violence, or even terror? How have revolutionaries attempted to establish their ideals and realize their goals? We will look at a set of major political transformations throughout the world and across centuries to understand the meaning of revolution and evaluate its impact. By the end of the course, students will be able to offer reasons why some revolutions succeed and others fail. Materials for the course include the writings of revolutionaries, declarations and constitutions, music, films, art, memoirs, and newspapers.
This module provides examples of the elementary circuit elements; the resistor, the capacitor, and the inductor, which provide linear relationships between voltage and current.
" This seminar has three purposes. One, it inquires into the causes of military innovation by examining a number of the most outstanding historical cases. Two, it views military innovations through the lens of organization theory to develop generalizations about the innovation process within militaries. Three, it uses the empirical study of military innovations as a way to examine the strength and credibility of hypotheses that organization theorists have generated about innovation in non-military organizations."
Students explore the composition and practical application of parallel circuitry, compared to series circuitry. Students design and build parallel circuits and investigate their characteristics, and apply Ohm's law.

" What is the history of popular reading in the Western world? How does widespread access to print relate to distinctions between highbrow and lowbrow culture, between good taste and bad judgment, and between men and women readers? This course will introduce students to the broad history of popular reading and to controversies about taste and gender that have characterized its development. Our grounding in historical material will help make sense of our main focus: recent developments in the theory and practice of reading, including fan-fiction, Oprah's book club, comics, hypertext, mass-market romance fiction, mega-chain bookstores, and reader response theory."
