Is the Singer Sewing Machine serial no. 2297800 Amperes .6 Catalog B.T.7 manufactured by the Singer Manufacturing Company worth anything?

Your serial number is off -- there should be at least one prefex before the number - one prefex puts it 1930 or lower and 2 Prefexis puts it at 1940 and up. You can go to the Singer site (link below) and find the year. Good luck!

Do higher wattage light bulbs draw more amps?
Yes, and it's proportional. V * I = P Where V is the voltage in Volts, I is the current in Amperes, and P is the power in Watts. So we get: I = P / V For example, with a 240 Volt supply, a 12 Watt lamp would draw: 12/240 0.05 Amperes, or 50 milliamps
The volt is the unit of measurement for?
Voltage, or "electromotive force" are measured in volts; electrical current is measured in amperes; and resistance is measured in ohms. They are related to one another by ohms law: E = i x r, where E is electromotive force, i is current, and r is resistance.
What are the advantages of transmitting electric power at high voltage levels?
For a given amount of power, the higher the voltage the lower the current. This is necessary to minimise the voltage drop along the transmission line, and to reduce energy losses which are proportional to current squared. The advantage of transmiting electrical power at high(er) voltages is that you can use smaller conductors, since the current flow would be less for the same amount of watts. Watts = Volts times Amperes
How many watts are consumed by a starter motor if it draws 150 amperes at 10 volts?
Power (W) = Current (I) X Voltage (V)Therefore a system drawing 150 Amps at 10 VoltsP=150X10P=1500 wattsor 1.5 kWAnswerWithout wishing to be pedantic, power is not 'consumed' by a load such as a starter motor. Power is simply a 'rate', the rate at which the load is consuming energy. You cannot 'consume' a rate, therefore, you cannot 'consume' watts! So your question should be rephrased to ask 'What is the power of a starter motor?', or words to that effect.
What do conducters and insulators do?
Voltage is the measure of electric potential, measure in volts. Resistance, measured in ohms, determined the resistance to the flow of current through a material. Current is the density of the flow of electrons past a point at a given time, and is measured in amperes (or amps). Ohm's Law best describes this interaction: E (volts) = I (amps) * R (ohms) So, voltage is equal to the amount of current (flow of electrons) flowing through a given substance times the resistance of flow of electrons. Imagine a pipe through which water flows. The amount of water flowing through a pipe is the current (gallons per second...analogous to electrical current, which is measured in amperes = coulombs per second...a coulomb is a large unit of electrical charge). The resistance, in this case, would be the size of the pipe and the placement of any obstructions to the flow. If you place something at the end to hinder the outflow of the water, you will increase the resistance, and this increases the pressure (voltage is like electrical pressure). If you increase the size of the pipe, you reduce the resistance, but the current doesn't change. If you leave everything the same and adjust a valve to reduce the flow of water, you will reduce the current (the flow), which also reduces the pressure at the end (the voltage). Conversely, if you have a wire, and you hook up a battery to the two ends of the wire, you are introducing an electrical potential to that wire, which will induce a current on that wire. The better the electrons can flow through that wire, the lower the resistance. Put some electrical load or component in the path of those electrons, and you will increase the resistance slightly, thereby reducing the current of the wire.
A current flow of 15.5 micro amperes is the same as?
15500 nano amperes or .0155 milli amperes or .0000155 amperes
What can you measure with amperes?
Current is measured in amperes. Amperes is also coulombs per second.
What are amperes measured in?
Amperes - they are the unit of current
What measured in amperes?
Amperes - they are the unit of current
How many volts can you get from 260 watts?
It depends on how many amperes there are. If you have 1 amperes, then you get 260 watts. If you have 260 amperes, then you have 67,600 watts. If you have 0.001 amperes, then you have 0.26 watts. Its just watts = volts times amperes. Of course, the limiting factor is the available power behind the 260 volts, but you did not say anything about that.
Is a kVa the same as an amperes?
KVa is not the same as the amperes because KVa is the unit for reactive power while amperes is the unit for current.
Can you change 8 mega amperes to micro amperes?
Can you be more specific?
How small is a nanoampere?
1 nanoampere is 1x10 amperes. That is 0.000000001 Amperes.
How many hours and minutes is in 233?
233 is just a dimensionless number. There are no hours, minutes,light-years, amperes, kilograms, or anything else in it.
What is measured in amperes a current voltage or an Resistance?
Electrical current is measured in amperes.
How many amperes are there in a kilo ampere?
Since kilo- means one thousand, there are one thousand amperes in a kilo-ampere, and there are 0.001 amperes in a kilo-ampere.
How many amperes could we tolerate?
The human beings have the ability to tolerate about 0.007 Amperes.
