What is meant by 26 amp hour batteries and how can we calculate the backup time of battery from this?
If you know how many amps your load draws then divide this into 26 and your answer will be the number of hours (approximately) you can sustain the load.
How do you calculate amp draw if you have a 25KW strip heater?
Divide 25,000 by the supply voltage to get the current.
How do i Calculate base current from collector current and resistance?
Ib =Ic /beta beta is the gain factor of the amp.
What produces more light series or parallel circuits?
A series circuit will produce more voltage. For example, two 12 volt automotive batteries both have a 600 amp capacity. Connect the 2 batteries in series and you will have 24 volts with 600 amp capacity. Connect the 2 batteries in parallel and you will have 12 volts with 1200 amp capacity.
How do you calculate ampere given 250v AC 60W?
Divide the watts by the voltage to get current (amps). 60W / 250V = about 1/4 Amp.
Can you use a time delay fuse in your central air conditioner of the same amp rating?
Yes, and you should use a time delay fuse.
What can a 15 amp circuit be used for?
The majority of the circuits in your home are run on 15 amp circuits.
Why use a Time delay fuse versus non time delay?
A time delay fuse will allow for a temporary spike in the current (up to 100 or 200% of the fuse rating), such as when starting a motor. A regular (non-time delay fuse) will not allow for any spike over the current rating of the fuse. If you have a motor that pulls 2 amps while running, but pulls 6 ampls while starting, then you will want to use either a 6 amp non time delay fuse, or a 2 amp time delay fuse. If you are talking about pyrotechnics, a time delay (properly called a slow burning) fuse will give you more time to run for cover.
Is it ok to run three 240 on one 50 amp breaker?
If you are asking, can three separate 240 volt circuits be run off of one 50 amp breaker then the answer is no. Not without knowing what the loading of the three circuits are and whether all three circuits could be on at the same time.
How do you get four twenty amp circuits from two twenty amp circuits?
Remove the two twenty amp breakers from the regular size slot and install two mini amp breakers. A mini amp breaker has two breakers per regular size slot.
How many circuits can you have off a 200 amp service?
As many as you wish, as long as you do cross 200 amp limit
How many 20 amp circuits can you run on a 50 amp service?
In the United States, there isn't a hard limit on how many 20 amp circuits that can be run on a 50 amp supply. This is because in most cases, especially in homes, we don't load most circuits with more than an amp or 2, even when they are protected by a 20 amp breaker. From a practical perspective you probably have a limited number of slots for breakers in your service or supply panel.
Can I put a 40amp 2pole breaker on a 1 horse power well pump I am using?
No, the breaker size is too big. A 1 HP, 230 volt motor draws 8 amps. The electrical code recommends for a motor with a full load amps of 8 amp that it use either 25 amp non time delay fuse, 15 amp time delay fuse or a 20 amp two pole breaker. These sizes will work up to 11 amp full load amps.
How do electricians check current flow in a circuit?
For AC circuits, amperage is checked with a clamp on amp meter. There is now in the market place a clamp on amp meter that will work on both AC and DC circuits.
How does the electric distribution panel work?
It's basically a system of circuits. The power from the mains enters through the input terminals. It's then split into various load circuits (5 amp for lighting, 13 amp for sockets , 15 amp for the immersion heater & 30 amp for cookers). Each of these circuits has it's own circuit breaker, which cuts the power to that particular circuit if the current draw exceeds the rating of the breaker.
What size breaker is used for a 5 ton 34 amp minimum 60 amp maximum?
60 amp using AWG # 6 copper for branch circuits.
What are the applications of adder and subtractor?
it can be used in op amp circuits, that is as comparitors or differentiators
