Want to test my circuit breakers to see which is using the most voltage?

If your panel and breakers are connected properly the voltage accross the "double pole" breakers should be 215 - 230 Volts AC (alternating current) The voltage accross the "single pole" breakers should be 105 - 130 Volts AC. All of the breakers should have the same voltage. If I understand your question you probably want to know how much electricity is being used on the different circuits in your house. The amount of electricity being used at a specific voltage is measured in Amperes or Amps (A) You would need to use a "clamp on" ammeter. They are relatively inexpensive. (probably between $75 and $500. follow the instructions that come with the meter but you would have to remove the cover at your main panel and clamp the meter around individual wires coming from each breaker. Remember the amount of amperage measured will depend on what devices are connected and running. For example: if you clamped on the circuit for your fridge it would read almost zero amps if the compressor was not running to cool the fridge. Measuring the "LOAD" or amount of power used on each circuit should probably be done by a qualified electrician.

Are circuit breakers more expensive the better they are?
On one hand you don't want to search for the absolute cheapest circuit breaker you can find.On the other this is a competitive business and most circuit breakers have similar quality and price ranges
What happens when you plug 120vac appliance into a 30 amp line?
Most 30 amp home circuits are 240 V. If you try to run a 120 V appliance using 240 V, the appliance will immediately self-destruct.However... if you actually have a 30 amp 120 V line to which you want to plug in your appliance, the only issue would be fire protection. Circuit breakers are in place to prevent too much current from passing through a wire. Wires have the capacity to carry only a specific amount of maximum current. a 10 Ga wire is generally used in homes for a 30 amp circuit. It doesn't matter if it's carrying 120 or 240 V, it still needs to be a 10 AWG conductor.However, you need to make certain that all conductors, outlets and circuit breakers are matched to each other when wiring a home or business.The appliance will only use the amperage that it needs UP TO THE MAXIMUM RATING OF THE CIRCUIT, providing that the VOLTAGEmatches.So the short answer is, just make certain that the line voltage is right for your appliance and that the circuit is rated at a high enough amperage to handle the appliance.
What part of circuit is not necessary for the circuit to be complete?
By definition an electrical circuit is a route or path that starts and finishes at the same place. So there is no part of an electrical circuit that is not necessary, because if there were it would not be an electrical circuit.An electrical circuit needs a power source. Conductors to transmit the voltage from the power source to the load. The final component of the electrical circuit is the load that you want to energize.If you remove any of the components there will be an open circuit and the load will be impossible to operate.
Are two pole circuit breakers 240 volts?
Yes, as long as you don't exceed the amperage of the breaker. Say your double pole is 30 amps. You want to run a clothes dryer that uses 10 amps, and a welder that uses 20. They both run off of 220v. You can dry your clothes when you are not welding. You can weld when you are not drying clothes. If you try to do both at once, you may or may not trip the breaker. Technically, you can run as many 220v plugs as you want, as long as you don't exceed the breaker's rating. Say you had a 5 amp air compressor, a 5 amp water pump, and a 10 amp clothes dryer. You can run all three at the same time. Just remember, as you increase voltage, you decrease amperage.
What size and type of wire should you use if you want to run 100 feet of 240 volt 30 amp wire through your basement to your garage to run an electric kiln?
As a minimum you need to run #10-2 AWG or 10-3AWG. (The extra wire is a Neutral for 110 Volts). You may want to use #8 AWG to make up for voltage drop if you are using something power intensive and it is a long cable run. You should also install a Ground wire and a GFCI to help to protect persons using the kiln from electrocution.Also ensure the correctly-sized circuit breakers are installed to protect the new circuit from catching on fire if there is a short circuit or some other type of current overload fault condition develops. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any workANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can some body show me Electrical circuit diagram of Molded case circuit breakers?
Circuit breakers do not have circuit diagrams. The breakers have an input where the distribution voltage is applied and an output where the load is applied. If you want to know what is inside a breaker, the electrical terminology to use is "shop drawings" of the specific breaker that you need information on.

Can you use electronic circuit as a load?
If you are just using the load to pull a small amount of current, then yes a electronic circuit can be used for that. If you want a resistive load to measure voltage drop or something similar, then no an electronic circuit will usually not work for that.
What would happen if the resistance in a circuit remained the same and the voltage decreased?
A well designed circuit should be able to operate over a range of voltages, not just at one voltage. Especially a circuit which is intended to be powered by a battery. As the battery starts to get used up, and the voltage drops, you want the circuit to operate as planned.
How do you check dc voltage... series or parallel?
If you are asking how a voltmeter should be connected in a circuit, then the answer is that it should be connected in parallel with the device across which you want to determine the voltage. This applies whether the circuit is d.c. or a.c.
How do you measur voltage in a circuit?
Place a voltmeter across the two points in the circuit you want to measure, and measure it. Be sure to know the expected voltage so that you can take appropriate safety precautions, and know the impedance of the circuit so that you can choose a voltmeter with a high enough internal impedance that it will not significantly affect the circuit.
What should be the secondary voltage of a transformer needed in a rectifier circuit if the required DC voltage is 6 volts using a?
A little more than 6 volts RMS, or 17 volts peak to peak (can get -6 and +6 voltage this way using a full wave rectifier). The voltage will depend strongly on your design - are you using circuitry that clamps the output voltage to a specific value (you should!). If you are doing this, I would find the cheapest transformer that meets the current capacity you need that has an output near the 6 volts you want.
Which charge is voltage carried by in an electrical circuit?
Well, first of all, voltage is not carried. Voltage is the 'pressure' between the ends of a circuit that makes charges want to flow. The charge carriers that actually do the physical flowing are the electrons, with their negative charges. When they flow, we say that there is 'current' in the conductor.
What is the advantages of using Thevenin Theorem?
Thevenin's Theorem is especially useful in analyzing power systems and other circuits where one particular resistor in the circuit (called the "load" resistor) is subject to change, and re-calculation of the circuit is necessary with each trial value of load resistance, to determine voltage across it and current through it.
You want to know about the voltage selector circuit using transformer?
the voltage selector circuit is used for converting input electrical energy through the voltage selection circuit,which is arranged within the transformer body with its two ends electric allay connected to an input port and an output voltage connection device must be plugged in a socket portion on the transformer body to initalize a micro control unit through feedback to change a volatage value sent to a voltage transformer unit and in turn change the voltage of output electrical energy until a display device displays an ideal output voltage value. Then, the user removes the connection device, and the voltage value of the input electrical energy is converted into corresponding to the selected
