No, resistance is the tendency to oppose the flow of electrons. Ohm's Law simply relates resistance, voltage, and current.

The armature has the stationary (not physically moving) magnetic field, which attracts the magnetic field in the rotor. Since DC does not alternate, a split ring is used to alternate the current (and resulting magnetic field), so that the rotor will spin.

the computer is what runs the car and all the engine functions, you can change the functions of the engine to get more power by buying a performance programmer and downloading the program into the cars computer.

theres your answer :)

On an electric bill, kVA stands for "kilovolt-ampere", which is a unit of apparent power. It measures the total electrical power, both real and reactive, that is consumed by a device or a facility.

It represents the maximum power that the electrical system can support and is used by utilities to determine the capacity requirements for supplying electricity to a customer. The actual power consumption in kilowatts (kW) is often lower than the apparent power in kVA due to the presence of reactive elements, such as inductive loads, which cause the power factor to be less than 1.

The barrier potential is not a voltage created inside the diode. instead, it refers to the depleted zone around the juncture.

Since this region is deplete from carriers (electrons or holes), it became a virtual isolator. In order to make the depleted zone conductive, you need to apply an external voltage to the diode terminals.

If the voltage is in forward bias (+ to the anode and - to the cathode), you will need 0.2/0.3 V for germanium diodes and 0.6/07 V for silicon diodes. You need an external diode to keep the forward current with safe limits.

If the voltage is in reverse mode (- to the anode and + to the cathode), you will need to apply much more voltage to achieve conduction, although this could permanently damage the diode. Zenner diodes, for instance, always work in reverse bias to create a stable voltage, which is used for regulation purposes.

Measurements and research from various sources tell us that

-1mA is the sensibility threshold.

-5mA to 10mA hurts.

-40mA causes heart disturbance.

-60mA to 100mA is lethal.

These are reactions of a healthy human body. Much lower currents could be lethal for persons with heart malfunctions, pacemakers or other implanted electronic devices.

The resistance of human skin is highly variable depending on several different variables, but the two main variables are whether the skin is clean or dirty. Clean skin often has a resistance of about 500 ohms. Dirty skin can have electrical resistances of up to several million ohms.

Ohm's law states that "The current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance in the circuit."

<<>>

if resistor exists, resistance decreases

according to ohm's law, current is directly proportional to voltage and current is inversely proportional to resistance

it means as current increases, voltage increases.

resistance increases, current decreases so as voltage

if there is no resistor, there should be no resistance except internal resistance of voltmeter and ammeter

Generator set, also known as genset, typically consists of components such as engine, alternator, control panel, fuel system, cooling system, exhaust system, battery and starting system, voltage regulator, control and protection devices, base frame and enclosure, etc. These components work together to generate electrical power and provide backup or primary power supply in different applications.

Positive aspects of becoming a computer technician include being able to fix your own computer. The job has room for growth, there is flexibility in career options, and computer technician jobs typically pay well.

the AC electric generator was invente by Nikola Tesla. He invented in the late to early 1800's and 1900's. This idea was recently accepted by scienctists.
According to the website linked below, it was invented in 1663.

I asked this very question to my professor in electronics 101 in college! He explained to me the load side of the transformer if not connected to any load is open. This is a great

resistance to completing the circuit. This is transferred to the primary side of the transformer as a great resistance thus no current flow.

On the main railway network, overhead lines use 25kV AC. In the past, some lines used 1500V dc overhead and 6.25kV ac overhead as well, but these have all been closed or converted. Tram and light rail systems use other systems.

The load current is made to flow through the thermal overload relay, which is actually a bimetalic strip. Beyond a prespecified current the bimetalic strip tend to deflect due to heat (thermal effect) thus cutting off the circuit and hence it acts as an over load relay protection.

Generac is a brand of generator, what they do will depend on the model you buy. Most models of Generac generators are set to switch on automatically in the case of the a black out but they also have commercial generators for use in business (particularly construction) and RV generators

A brick wall is not a sufficiently good electrical conductor to act as part of an earthing system. There is no substitute for a proper system.

Work is usually measured in joules, which are a unit of energy. Work/time is called power and is usually measured in Watts (joules/second) other common units of power include Horsepower and ft*lbs /sec.

in short, is is power, which is measures in watts.
