Hi, i`m not sure if you know or not but the fuse is really a very small resister.

the main power fuse is located near the power jack on the circuit board.

this is the number you need to look for F0001. if you have a digital meter set it to 20K

and test the fuse/resister. the fuse should read the same way as if you touched the two meter leads together.

hope this helps you.

good luck.

depends on the number of cans and the specific gravity of the electrolyte

This is a very technical electrical question that may be difficult to understand without further study. But adding appliances to an outlet is the same as adding resistance in parallel. Adding resistance in parallel, the resistance of the circuit goes down. That is why you get more current flow.

By contrast, adding resistance in series increases the resistance of the circuit and therefore reduces current, all else being equal.

A strange but enlightening question. One can view ALL ELECTRONICS as making and modifying V/I curves. All the circuits and tools you have seen are ways of doing this.

From your description, this sounds like it is a sine wave offset to 10A, so the peak is at 20A, and the min is at 0?

For this case, you have 10A DC (RMS) wave and a 10A Peak - neutral AC wave; The RMS value of the AC wave is: 10/2*sqrt(2) = 3.54A.

So the RMS amplitude of this wave is 13.54A.

The 74138 is a 3 to 8 decoder. When enabled, one of the 8 outputs is low, based on the binary value of the 3 inputs.

Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.

The current, if connected to a voltage source that can supply the needed current to (R1+R2) R3, will be unchanged.

If the source cannot supply the needed current, the terminal voltage will decrease, which will change the current flowing through R1 and R2.

Transformer cores are chosen to limit eddy currents, which cause heating and losses in the core. Very thin laminations minimize this overhead cost of running a transformer by reducing losses associated with eddy currents.

Auto regulation (intrinsic) is when a cell, organ, or organ system automatically adjusts itself in response to a change in the environment. Extrinsic regulation involves the nervous and/or endocrine system detecting a change and sending a signal or releasing a chemical to facilitate change in another organ system, organ, or cell.

This depends on the voltage, and whether it is a three phase or single phase transformer.

Below 24 volts: low voltage cables are like other cables but without so much insulation. They are made of copper and insulated with pvc, usually only one layer. They are most commonly used in cars.

Many banks will hire an electrical engineer to assist with their online, phone, and e-banking systems. The engineer will be working with the networking and hardware to insure the systems are running properly.

11000 V generator is best as it generates higher Voltage

Profits:

1. Fuel saving,

2. Place Saving,

3. Less Pollution,

4. 11000 V can be step down as per requirement using modern equipments.

5. Least maintenance,

Losses: As single unit generator 11000 V, if there is Break-down, all Collapse. And

in 415 V multiple units are using so effect of Break down less, and easy maintenance. there might be less effect of B.D.

VA refers to the effective load that is placed upon the Control Transformer (also known as Selection Inrush VA).

I think you mean the meter is rated at 1K ohms per volt. It means that with a series resistance designed to give FSD at any required voltage, the total series resistance must be 1000 ohms per volt (100K ohms for 100volts) . This is because 1K ohms per volt is just another way of saying that the full scale reading occurs at 1mA current. In that case a full scale deflection for 100 volts applied, 1mA is obtained with a total resistance (meter + added resistance) of 100 kOhms which is your loading resistance.

It might be.

Or it might not.

You need to specify the transformer's turns ratio or its impedance ratio, and th eload on the secondary.

Yes, but the motor's horsepower rating will not be reached.

voltage is devided only in series circuit and is the same at the parallel circuit

You need the machine open circuit saturation curve as well as the zero power factor test results to obtain the best possible answer. Once you have that you can draw the potier triangle and obtain the value analytically. Please tell this forum if you have these results and I can help you further. Because it involves graphical analysis, it would be easier to e-mail something. I can't find a way on this forum to add any form of graphics..pity

Begin with the most basic. Ohms law. I=E/X. Don't know I or E? Then the formula is, XL= 2 x pi x f x L. That is Inductive reactance equals 2 x 3.1416 X frequency in hertz x inductance in henrys.

If frequency is in MHZ, HF. VHF. UHF., radio frequencies, reactance in inductors/coils is small and requires no conversion if the values are expressed in microhenrys and megahertz.

If the question is not just a simple test question and you are dealing with a real world application, one must remember that current runs 90 degrees behind voltage, which is the opposite of the capacitor current-voltage relationship.

hello...

This is a very vague question, so I cannot give a very specific answer. However, I can give some pointers for anyone who is interested. First, I'll provide background info for anyone who is new to electrical repair.

A short circuit (a.k.a. a short) is the result of the positive side of the battery connecting to the negative side of the battery (when a wrench accidentally falls across both terminals of a battery, for example). This can also happen when the positive wire of a device hits the chassis of your vehicle.

To fix a short, you must find it's location and cause. Do this by checking for blown fuses and / or tripped circuit breakers. Then check your owner's manual (or relevant service manual) to see what circuits are protected by that device. Afterwards, check the wiring of every device in the system. Correct the cause of the short (it could be a chafed wire, poor electrical connection, or even a miswired device causing the trouble) and you should be good to go again.

I hope someone finds this helpful. Peace be with you all!

Imagine life without electricity. When sun set, all you see is dark. No television and radio that connects you to other and give information. Electricity help your daily life easier and more enjoyable. Electrical equipment can replace a human task.
