During discharging, the ions flow back through the electrolyte from the negative electrode to the positive electrode. Electrons flow from the negative electrode to the positive electrode through the outer circuit, powering your laptop. When the ions and electrons combine at the positive electrode, lit...
How long exactly depends on the strength of the electric current you use and the concentration of the electrolyte. Increasing either of these increases the speed at which ions and electrons move through the circuit and the speed of the plating process. As long as ions and electrons keep moving...
What causes the electrons to flow in a wire? Explain how the phenomenon known as electromagnetism relates to an electric motor. Explain how a 'solenoid' wire works. A conducting loop around a bar magnet begins to move away from the magnet. Which ...
Note: As you can see in the previous diagram, Zener breakdown occurs at a much lesser voltage. Hence, we can use this property in the circuit as a circuit breaker. Wherever the voltage across a Zener diode is above a certain value, it offers a low resistance ...
If I have 3 identical light bulbs in a circuit, why would one of the bulbs be brighter than the other two? Explain using equations. A 100 w light bulb is left on for 10 hours. Electricity is 10 cents per kilowatt-hour. How much d...
A circuit is a path provided to allow electrons to flow. A circuit allows the energy from a power. Series and Parallel Circuits Circuit Warm-ups There must be a positive and negative in everything in the universe in order to complete a circuit or circle, without which there would. ...
Let's take a closer look at ICs and how they work!Photo: An integrated circuit from the outside. This one comes in a convenient form called a dual-inline package (DIP), which consists of a black plastic or ceramic outer case with metal pins down each side for plugging into a bigger ...
The electrolyte is a thin membrane made of a special polymer (plastic) film and only the protons can pass through it. The electrons, meanwhile, flow through the outer circuit. As they do so, they power the electric motor (orange and black) that drives the car's wheels. Eventually, they...
In this example, if we have a flow of electrons into the page, the conventional current flows out of the page (so that's the direction in which your second finger should point). If the field flows from left to right (first finger), our thumb tells us the electrons will move upward....
When sunlight shines on a solar cell, the energy it carries blasts electrons out of the silicon. These can be forced to flow around an electric circuit and power anything that runs on electricity. That's a pretty simplified explanation! Now let's take a closer look...How are solar cells...
