### Unknown circuit component with glass encapsulated contacts

It looks to me like a reed switch (I can't be really sure though because the image is not clear enough). A reed switch is an electrical switch operated (usually) by an applied magnetic field. A ...

### Help with closed loop heat controller (for a non engineer)

Since you seem to not be too familiar with control systems, electronics, and wiring things, I recommend a simple threshold detector that controls a relay. The relay then switches the heating element ...

### Units for plasma etching of circuits: A (with degree symbol)/min

Anisotropic etching is a linear process, like welding, so presumably the units would be distance per time. Unlike welding it is at a small scale. See this slideshare. In this case units are Angstroms ...

### In the equation for power as a function of current and resistance, what do the two factors for current represent?

Firstly, by temporal I think you mean spatial. Secondly if you consider acceleration, the units are m/s^2. Seconds-squared are not spatial, but they are temporal. But they needn't be either. Consider ...

### Designing a Voltage Divider

R2 and RL are in parallel so the voltage across them will be the same so can be treated as a single resistor when thinking about the voltage across them. So Req(lower) = (1/R2 + 1/100kohms)^-1 Req(...

### Looking for a device that breaks the circuit if the voltage gets too low

The simple answer is that you can get off the shelf modules which does exactly what you want. They are often called 'split charge modules' and are designed for installations like boats and motor-...

### What is the purpose of the capacitors on LDO Regulator Circuit?

The capacitors serve two distinct functions They serve as "reservoir" capacitors. If the regulator is somewhat remote from the energy source then sudden current peaks will cause $V_{in}$ to dip due ...

### Clarification on how current flows from a socket into a device

My understanding is that when you have a circuit with that's connect to a battery they has to be some resistor in the circuit of some kind to ensure the current on the wire is small enough to power ...

### Help with closed loop heat controller (for a non engineer)

In my experience getting data from a rotating component is tricky without resorting to some kind of radio transmitter or a passing the data through a slip ring, which would probably require ...

### Is there current multiplier circuit?

My input is DC from a small DC motor which I use as a generator. My input current is 300 milliamps and I need 1200 milliamps as output. Is there some way to increase the output to 1200 milliamps ?...

### Using Stainless steel or iron pots in oven

If it was a microwave oven then all metals can damage the oven if they are placed in the oven & the oven is operating. If the oven is is thermal oven that is heated by an electric element, gas or ...

### How do I calculate voltage at an LED in parallel?

One good place is to start is LTL-307EE datasheet. From the datasheet take look at current profile for the device. Below is the forward current and voltage characteristics. Also take look at ...

### Electrical potential and grounding in a circuity, why it works?

The issue is certainly NOT that the chassis ground is at -100V, it's absurd. The chassis ground by definition is at equal potential for power supply and load, you can treat it like one big wire that'...

### SolidWorks circuit simulation?

CircuitWorks doesn't simulate the electronics; it just integrates between some common PCB design software formats and SolidWorks for mechanical information. For example, maximum component height, ...

### Is battery-charge-stop-at-XX-percent circuitry not cheap?

IBM/Lenovo ThinkPad line is basically the only manufacturer/brand of mobility devices that includes circuitry and software that allows one to vastly prolong battery life of laptops used as stationary ...

### How do you find "this" Vx in the given circuit?

You start by making A-B an open circuit. This implies that the current entering or leaving node A from the load is 0 Amps. This implies that the current in the two 1 $\Omega$ resistors have the same ...

### How do you find "this" Vx in the given circuit?

You are right in that $V_x$ can't be 10 V. Fortunately, 10V for $V_x$ simplifies the circuit considerably, making it particularly easy to analyze. Since $V_x$ is the same voltage as the supply on ...

### How do they get more signals simultaneously inside a node of a neural network?

First off, neural networks are only very rarely done in hardware, as actual summation of electric signal. Much more often they are just programs that run on standard computers, simulating a network ...

### How would I measure this battery circuit with a multimeter?

If you trying to measure voltage, connect the black connector probe (Terminal) to COM. Move the rotatory switch 20 DCV. The dot should point to 20 DCV. Then place the black exposed probe to negative ...

### What's the most practical way to measure angular velocity for small rotations?

I'd use a video camera and attach a striped pattern to form a moire pattern which is easy to see in the video. Here's a link: [http://www.unappel.ch/people/emin-gabrielyan/public/070804-multi-ring-...

### Simulation of RC circuit using Proteus

Try using a replacing a 9V VDC voltage source with a VAC voltage source. Pay attention to the frequency of the VAC voltage source. This should address the issue. With regard to determining the time ...
