If the probability of an event is 0.02, then the probability of two such events occurring is 0.022 or 0.0004.

What does independent variable mean in electricity?
An independent variable is something that you, as the experementer, change to try and get a set of results. E.g, in an electrical ciurcut you may change the voltage to see how it affects resistance. Voltage is the independent variable as your changing it, resistance is the dependant variable as it changes due to the change in the independent variable.
What is the probability of getting electric shock?
For mains electricity it is close to 0 if you behave responsibly. For static electricity it depends on the environment that you live in: indoors in cold climates, with synthetic fibres in carpets and dry air, the probability is quite high. However, many people will not register the shock even if there is an electrical discharge.
Application of Z transform in electrical?
Z tranform can be used to solve the differential equations occurring in electrical problems.
How much water does an electrical hot water tank hold?

A certain airplane has two independent alternators to provide electrical power The probability?
Two alternators are used as a safety measure. The probability of both alternator failing are very minimal. Many planes use redundant systems.
A certain airplane has two independent alternators to provide electrical power what is the probability that a given alternator wil fail on a 1 hour flight?
There is insufficient information for us to answer this question. Please edit the question to include more context or relevant information. It would be useful to know the following:The failure rate of each alternator;Which of the two alternators is the "given" one.
What is the Delco alternator used for?
The Delco alternator is an electromechanical device that converts mechanic energy into electrical energy. Most alternators are used for rotating magnetic fields with a stationary armature.
Do new cars still have alternators?
Yes, most definitely. The alternator keeps the battery charged and runs all the electrical s in the vehicle.
Where is the voltage regulator located on a 1993 Ford Thunderbird?
Most modern alternators have the voltage regulator inside the alternator housing, so you have to take the vehicle to a automotive electrical shop to have the electrical system tested, unless you want to pull the alternator and take that in.
What charges an alternator?
Alternators convert rotating mechanical energy into electrical energy. Alternators produce electrical energy by induction of the coil wires by the spinning electromagnet rotor. The back voltage and eddy currents produce a magnetic field that opposes the rotation of the rotor, conserving total energy.
How do 1 wire alternators work?
A one wire alternator has one wire that sends electricity to the battery and electrical system. They usually always have an internal regulator.
Why does your 01 Oldsmobile aurora keep burning up alternator?
Alternators Repeatedly "Burning Up"It is obvious that you have a very serious defect in either the charging system, or the electrical system of your vehicle.It appears that the problem is not with the alternators, but somewhere else in the charging or generic electrical systems.Due to the high cost of alternators, and the labor to reinstall, I suggest that you take your vehicle to a bone fide auto repair shop and have a PROFESSIONAL auto electrical Technician hook up his computer diagnostic machine to your Olds and run a full diagnostic analysis of all electrical systems.
How much voltage does an alternator put out?
Automotive Alternator Output VoltagesWith a properly operating alternator, AND electrical system, a voltage output range of 13.5 Volts to 16 Volts is considered acceptable.Just the alternator puts out around 120 vac, but most newer alternators include a built in rectifier that limits voltage output to between 13.5 and 15.5 volts DC depending on speed.
What determines electrical supply frequency?
The speed of the alternators and the magnitude of the load.
How can you tell if you have a bad alternator in a 1991 Ford Ranger 2.9?
Easiest way is to check the voltage your getting out of it when you have electrical loads on (headlights, radio, blower) If the alternator is faulty the voltage would be low
How do i know my alternator is working?
Is My Alternator Working?I take my vehicle to one my local nationwide auto parts stores [like Autozone, O'Reilly, etc.].They have handheld, portable, test equipment with which they can test alternators, batteries, and electrical systems on my truck while in their parking lot.In our area [SE Texas] these testing services are free.
