There are several ways, like a schmidt trigger (for one) and a lot of it depends on what you're trying to accomplish and the circuits you're trying to work with. The question is too general to give you a complete answer.
Can you use 220 volts to 240 volts?
Each voltage has a range and devices rated in that range will all work . The 110 to 120 volts is one range of voltages. The 220 to 240 is another range of voltages. The reason there is a range of voltages is to help the utility company out. They are mandated to keep the voltages within a + or - 5% range of a set voltage. Because there are loads coming on line and loads dropping off line the voltage...
How can you change a 200 volt socket into a 240 volt socket?
You do not need to. Each voltage has a range and devices rated in that range will all work . The 110 to 120 volts is one range of voltages. The 220 to 240 is another range of voltages. The reason there is a range of voltages is to help the utility company out. They are mandated to keep the voltages within a + or - 5% range of a set voltage. Because there are loads coming on line and...
What size resistor in parallel to reduce from 120 volts to 100 volts?
A resistor in parallel with a voltages source will not cause the voltage to drop, theoretically. To get a 20 volt drop you need a resistance in series, and the number of ohms is 20 divided by the current in amps. If the current is unknown or variable, the voltage can't be dropped by using a resistor. ...

How many amps are required to start a 5.7L engine?
Starter draw is typically under 100amps. The battery has to be in good enough shape to take the 150 amp (fuel injection, pump, and ignition) draw plus not allow a voltage drop below 10 volts. Coils don't really fire well at lower voltages if at all. ...

What is the volt drop on a cable 912 meters 480 volts and load of 54 amps?
The volt drop on a cable 912 meters 480 volts and load of 54 amps is 5% if you use 2/0 AWG wire and 2.4% if you use 300MCM wire. See Related Links below ...
How do you drop 240 volts ac down to 80 volts ac?
The most common way of dropping AC voltages is with a transformer. 80 volts is not a common secondary voltage. This type of transformer would be manufactured for OEM (Original Equipment Manufacturer) only equipment and not for the general public. A motor shop might be able to wind one for you if you have a transformer core that they could use. You would have to let the winding shop know what the connected load current is at 80 volts. ...
How much ohms resistor is needed to drop 12 volts to 5 volts?
Calculating voltage drop across a resistor requires that you know the current flowing through the circuit. The resistance needed is the voltage drop divided by the current. ...

Is 550 volts common?
In Canada 575 - 600 volts is a very common commercial and industrial voltage. It is supplied as a three phase four wire system. Being a star (wye) connection the voltages are 347/600. For high bay lighting installations, the fixture's ballast has multiple taps for different supply voltages. One of these taps is for use on a 347 volt supply. This allows both lighting loads and three phase loads to be supplied from a single service entrance drop. ...

What gauge wire is needed for 200 feet with 110 volts and 50 amps?
6 AWG will handle 50 amps with a voltage drop of about 4 volts. If you go to 4 AWG and limit to 50 amps your voltage drop will be 2.5 volts. ...

How do you calculate the ac amps when you have the DC volts DC amps and the ac volts?
the answer is dc volts are rectified from ac volts and the amperage will be the same unless you account for the slight drop from the rectifier. dc volts from a battery have no relationship to ac volts. you can derive ac volts from a dc source using an inverter. ...
How do you reduce neutral and earth voltage up to 0 volts?
The neutral and earth voltages will be equal when no current is drawn from the supply. The neutral is earthed at the supply transformer, so it may have a small voltage to earth equal to the voltage drop in the neutral wire from the transformer to where the measurement is made. ...

If we have 13 volts on earth and neutral so?
The neutral and earth are connected at the supply transformer, so 13 volts on the neutral means that you are far enough from the transformer to have a 13 volt drop on the neutral. You probably have the same drop on the live, so the total volt drop could be 26 volts, which may be excessive. It could indicate a fault somewhere. ...
How do you reduce 12 volt DC to 9 volt DC?
Nowadays, you can buy DC to DC convertors that do the conversion in a single module. A cheaper solution, however, would be to use a chain of diodes - each diode will drop 0.7 volts so 4 diodes will drop 2.8 volts, reducing 12 volts to 9.2 volts. ...

What resistor or resistors could be used to drop a current 2 volts?
If you want a voltage drop of 2 volts across a resistor, then its resistance must be ( 2 ) divided by ( the current through the resistor, in amperes ) ohms ...
How much current will flow in a simple series circuit with a voltage drop of 10 volts another drop of 8 volts and a total resistance of 2 ohms?
Current, by Ohm's Law, is voltage divided by resistance, so, 18 volts divided by 2 ohms is 9 amperes. ...
Can you plug a 120 volt appliance into a 115 volt outlet?
120 Volts and 115 Volts refer to the same thing in the US. Residential electricity is provided at 120 Volts from the utility. High current devices such as motors are often rated at less than the supplied voltage (such as 115 Volts) because it is expected that there is a small amount of voltage drop in the circuit feeding them. The National Electric Code allows a 5% drop in voltage from the electric service so a 5 Volt drop from 120...
How many volts does it take to start a buick?
The normal battery voltage is about 12.6 volts with no load. Anything much less than this indicates the battery is not fully charged or is degraded. The key to starting an engine though is what does this value drop to when you start to crank the engine. If the battery is weak and the engine does not crank, the voltage could drop below 10 volts. If your car has a voltmeter in the instrument panel, note the value without cranking and...

What value resistor would you need to drop voltage from 12 to 1.2 volts?
Doing it with a single resistor is not a good idea because it can only be done with exactly the right amount of current. If the current is 1 amp, for a voltage drop of 10.8 volts you need 10.8 ohms (volts/amps). ...
