(2) itallows us to be introduced to some circuits that have importantengineering applications.The sources in the circuits discussed in this chapter are lim-ited to voltage and current sources that generate either constantvoltages or currents; that is, voltages and currents that are invari-ant ...
An exploratory case study involving six grade 9 science teachers was undertaken to probe how teachers' understanding of learners' misconceptions relate to their perceptions about teaching simple circuits. The participants' understanding of documented misconceptions in electricity were explored by means of a...
Electric Circuits To make an electric circuit, we have to get electrons to travel in a continuous circle through a device that can change their energy. For example, a light bulb is something that can turn the moving (kinetic) energy of the electrons into light. Components of a Circuit Circu...
interconnection of the five regions consists of just 16 400-kVAC circuitsand five DC circuits (totaling 5000MW), and the highest operating voltage is only 400kV. These lead to the low capacity and poor security. Insufficient capacity and old equipment are common problems for the distribution net...
The study was conducted in two sixth-grade classes taught by the same teacher, in six lessons that constituted a third of a unit on simple electric circuits. In these lessons, one class was assigned PS tasks where students were asked to solve conceptual problems. Later they were asked to ...

Hello all, I'm trying to simulate simple electric logic (asynchronous) circuits. By "simple" I mean that I only want to know if I have "current" or "no current" (it's quite digital) and the only elements need to be (with so

A relatively large number of dimensionless quantities involve both electric circuits and fields, and are as diverse as electrothermal, ionization and corona diffusion processes; natural and forced electrothermal convection; heat transfer intensification with dielectric fluid condensation; condensation in an ele...
