### 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 ...

### 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-...

### 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 ...

### Can a 0.5 W resistor be substituted for a 10 W resistor?

No. Here's why: As current flows through a resistor, heat is generated as electrical power is dissipated. That heat flows out through the walls of the resistor, the inside of which is hot. Too much ...

### 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 ...

### 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'...

### 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 ...

### 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 ...

### How can I create an RL circuit?

Try this. Figure 1. A simple snubber indicator. Pressing SW1 will pass a current through L1. D1 will be reverse biased and LAMP1 will remain off. Releasing SW1 will cause L1's top terminal to switch ...

### Explanation for photovoltaic circuit

Diode Like you assumed Panels: These are the PV panenls that produce current. They produce DC current I and DC voltage V Inverter: the inverter converts the DC current and Voltage from the panels to ...

### What is the purpose of the resistor in this circuit

Power supply schematics like this one often contain an arbitrary load resistance just to specify where the output of the circuit is taken off. It is not part of the power supply circuit itself.

### Mackie CR3 bookshelf speakers only play incredibly quietly on max volume

This is a standard issue diagnostic issue. We could send you to an audio equipment SE but diagnosing issues is what I do for a living. You say you have already checked most of these but the order I'd ...

### What signals are expected on the connectors for this 12V Volkswagen Scirroco wiper motor circuit

As indicted in the comments usually the VDC for traditional automotive is 12 VDC nominal, though in most cases it is 14 VDC. Looks like the below image is from a similar configuration. If the part ...

### Utilize multiple vehicle power outlets to increase wattage capacity of inverter

It is possible that the outlets you want to pair together may have the same supply : relay and / or fuse... You should connect a set of wires with appropriate fuse directly to the battery, if this is ...

### How do you create a negative and positive voltage(-6V and 6V) with a singular voltage source?

Below is a simple circuit that I have used to create dual power supplies with a single power source for prototyping purposes. Depending on the current draw size resistors and capacitors. There are ...

### How can I calculate overcurrent from over voltage for the AP9101C IC

don't know whether you resolved this. Answer: Your part has one of the lowest over current thresholds (60mV in table), pick a higher voltage. Unfortunately I can't see how the voltage translates to ...

### Designing a loaded voltage divider?

Your circuit works. Proper ground connection. Your battery would be +12V -(-8V) = 20V. Voltage at Point A = 12V, Point B = 9V, Point C = 4V and Point D = 0V. The circuit is a good place to start. ...

### Cannot understand an equation related to impedance. (Power system analysis)

$\underline Z$ is, by definition, $\frac{\underline V}{\underline I}$. So $\underline Z$ is not shown, but it comes from the calculation for $\underline V$ as a function of $\underline I$. The ...
