Have a alternator that is 6 inch across and 4 inch back to front no information on alt what is its voltage and amperage?
Look very closely for a serial number stamped on the unit. The suggested course of action is to take the alternator to an auto parts store to see if they can recognize what vehicle the alternator should belong to. Automotive alternators are three phase and should have a full wave diode bridge concealed within the alternator housing. If you open the alternator case, the diode bridge will have diode numbers or a number stamped on the bridge network. Cross referencing this number to other diode bridges will tell you what amperage the alternator should be able to output. If you find a number there let the automotive parts store see if they can find a substitute for it.

How do you measure the current by using multimeter?
The current is the amperage. It is measured in series. Voltage is measured across the line (parallel).
Four 9 volt batteries are connected in paralell how much voltage is active across the circuit?
9 Volts. By connecting this way you increase current potential (amperage) but not voltage.
Can 50 Hertz multi tester be used on 60 Hertz 220 volts for testing voltage?
Any of the multi testers that I have come across are not frequency sensitive. I use a Fluke process meter and it can be used to measure frequency if that scale is selected. Voltage is voltage, amperage is amperage and resistance is resistance regardless of what he frequency is.
Voltage across resistor is doubled the current is?
Ohm's law states that the voltage across a resistor is the product of the current times the Resistance or V=I x R (I times R). V is Voltage, R is Resistance, and I is Current or Amperage. So if the Voltage is doubled and Resistance stays the same, the Current will be doubled.
How do you check Subaru alternator?
The easiest way to check any alternator in a car is to have the vehicle running and use a VOLT meter to read across that battery terminals. The voltage should be in the range of 13.4 volts to 14.5 volts..no lower, no higher. If either low voltage or high voltage exist, that alternator is probably defective.
Why does the engine shut down when the battery cable is removed on your 2005 ford focus?
Alternator is rated at 110 amps. The alternator should provide the voltage required to run the engine. It should handle the system current load. Check the alternator if there is a charge voltage. Turn the engine off and measure the voltage across the two battery terminals with a DC volt meter. Start the engine and measure the voltage across the battery terminals. Look for an increase in voltage on the volt meter. Typically it can go as high as 14.7 volts. If the voltage stays the same as when measuring the across the terminals with the engine off, the alternator is probably bad. If the voltage is charging but not much higher than when the engine is in the off position, some diodes could have burned out in the alternator. Also check the charging wires and ground wires coming from the battery.
What is the formula to compute the amperage of a ring in magnetic particle testing?
The formula to calculate the amperage of a ring in magnetic particle testing is Amperage = Voltage / Resistance, where Voltage is the potential difference across the ring and Resistance is the total resistance of the ring. The amperage determines the magnetic field strength generated by the ring to magnetize the test specimen for detecting any discontinuities.
How can you tell if its the battery or alternator that's not working on a car?
Start car. Turn on all lights, blower etc., that you can. Read voltage across battery terminals. If voltage is 13.5 or more then your alternator is okay. This assumes you have clean connections, good cables.
How does voltage regulator works?
A Voltage Regulator is just a Zener Diode that is wired across the alternator terminals. ... no. Doing this will blow the zener - don't try it at home or anywhere else.

What two things happen when the number of appliances connected to the multiple socket is increased?
The amperage of the circuit increases and the voltage drop across the appliances will tend to increase.
How do you determine the amperage given the voltage and power dissipated?
Like Ohm's Law, the formula for calculating power is a simple product of two quantities. It is given by the formula P = VI, where V is the voltage in volts and I is the current in amperes (or simply amps). So, if you know the value of any two of the quantities, you can easily calculate the third with simple arithmetic. For example, if the current flowing through a resistor is two amps and the voltage drop across that resistor is five volts, the power dissipated by the resistor is, P = VI = 5 volts * 2 amps = 10 watts. If you are given the power and the voltage, you can easily find the current. For example, if you are told that the voltage drop across a resistor is five volts and is dissipating 10 watts, the current through the resistor is 10 watts/5 volts = 2 amps.
