Q:how to measure the output power of generator ?
Connect a high power AC current meter or watt meter between the output and load. Connect a voltage meter across the load. Increase the load until voltage drops below 10% of its rated voltage. Read the wattage or current from meter. Or calculate it W current X voltage ( obtain from meter) The simple way without those expensive current meter or watt meter and variable load Connect some known wattage device like heaters in parallel one by one until you see the voltage drops down 10% below its rated voltage. Add all the loads wattage is the approximately answer.
Q:What would you do with your powers? Why?
i'd want to be like jean as in x-men
Q:I am just doing research on building my power system for a van. Now from what I understand the charge controll?
if something is producing a current of 40 amps with an energy rate of 5000watts it is creating a voltage of 125 volts. if something is producing a voltage of 12 v and 80 amps of current are flowing then 960 watts of power are involved. You have used the term 12v battery bank. This implies that there is a set of 12v batteries. Each battery is capable of being recharged independently if only the correct circuitry is provided. Each battery in such a system would be the limiting factor in the time taken to recharge the battery. If too much current is driven through a battery heat can accumulate and destroy the battery. There is insufficient information here to determine what can be done safely. The details of how the 12v batteries are built determines how rapidly they can be recharged.
Q:4 federal & state government powers please?
Collect taxes, make laws, build roads, maintain a court system, See concurrent powers
Q:Is it safe to use a power inverter in a battery bank cupboard?
It would be safe, BUT you must remove the heat generated in that room, preferred method would be forced air. drilling a few holes about 6-8 inches below and door opening and above the floor and then placing a vent register such as used for heating in a home would help to dissipate the heat much quicker than straight force air.
Q:can i charge power bank on 550 Mah wall charger ?
First, you should know that ONLY BATTERIES have mAh ratings. The h means hour. Chargers have only mA or A ratings. No h. Ever. Since 550 mA is only a little more than 25% of 2 A (2000 mA), there should be no problems. Phones have charge controllers in them, so that should work, too.
Q:How do I get power of attorney, my brother lived in California he died in Texas, I need to settle his estate?
Go to a lawyer
Q:If you could have a super power, what would it be? You also get a secondary power, but?
Reading minds and super strength
Q:Do you seriously believe a government/banking monopoly over our money is a good thing?
Well of course not, but who aside from Ron Paul has the balls to challenge the system?
Q:Engineering Homework Help! Circuits 3 phase power systems, delta connected load, power factor?
This is more less an arithmetic problem. Here are the steps. 1. Determine R and L of the motor. You know power, voltage and PF. 2. Determine the desired load (Zload) in order to get an overall PF of .9. 3. Determine the required capacitance from you knowledge of Zload.
