How many amps are in a C battery?
The amperage drawn from a C cell battery is governed by the load resistance. The lower the resistive load the higher the amperage draw from the battery.

How much can a 6500 watt generator handle?
A 3500 watt generator used in North America has two outputs. A single voltage of 120 volts or a 120/240 volt output. The larger size generators usually have the dual voltage outputs. Using the formula I = W/E, Amperage equals Watts divided by Volts we can calculate the amperage output of the generator. Single voltage generators will be 3500/120 = 29 amps. A dual voltage generator at 240 volts will be 3500/240 = 15 amps. To calculate what devices the generator will operate, add up all of the amperage's of the devices you would like to operate. If the added load is higher than the calculated output the generator breaker will trip. If the calculated load is lower than the calculated output of the generator, the connected devices will operate. If there is a motor being connected to the generator keep in mind that you have to use the motors full load amperage and multiply it by a factor of 3. This is because when a motor first starts, the generator will be looking at an almost dead short, with a high amperage draw, until the motor starts turning. Once the motor starts turning the amperage drops down to its normal operating amperage.
Why are the actual freezing point depressions of electrolyte solutions slightly lower than the calculated values?
Because of ion attraction
Why is it that the thicker copper wire the more amps produced?
A wire does not produce amps. A wire with a larger cross sectional area allows more amperage to pass through it with less voltage drop due to a lower resistance.
When a circuit is inductive the current has what voltage?
This doesn't make sense, "current" is "amperage" so the higher the voltage the lower the amperage, and the lower the voltage the higher the amperage.
Can you run a motor of greater amperage draw with a motor of less amperage draw?
It looks like you are asking if a higher amperage motor can replace a lower amperage motor. It depends on what the amperage difference is. If the amperage is high enough to move the capacity of the wire out of its rated value then it should not be done.Remember motor conductors have to be rated at 125% of the motors nameplate amperage. As the amperage increases so does the HP and the motor's protection will also have to be increased or the motor will trip the lower overload protection settings.Also keep in mind that if the motor is three phase, running a motor with higher HP on a load that does not need the extra HP, it will lower the power factor of the supply distribution.

What size breaker is needed for a 125 hp motor?
It depends on what the amperage of the motor is. The motors amperage depends on the voltage of the motor. The higher the voltage the motor operates on the lower the amperage. So unless the amperage from the motor's nameplate is stated an answer can not be given.Just remember that the feeder capacity to the motor has to be 125% of the motors full load amperage and the breaker protecting the conductors to the motor has to be rated at 250% of the motors FLA. This higher breaker size allows the motor to start without tripping a normal size breaker that is rated for the lower conductor size.
What will happen to a motor if it is supplied with lower voltage than its rated voltage?
The amperage to the motor will go higher.

Can you reduce amperage by using thicker wire with a constant voltage?
The amperage flowing through a wire is directly related to the load placed on the circuit, and has nothing to do with wire size, except that a larger wire will carry more amperage. Increasing wire size will not lower amperage but will allow the circuit to carry more amperage if the breaker is also increased in size. No. Ohm's law tells us that V = IR. For a given load, R is constant, and thus the only way to reduce current is to increase voltage.
What are the parts of the organs marked by boundaries?
Lobes are the part of the organs marked by boundaries. The human anatomy is divided into two separate parts; the upper and lower body.
What is the effect on battery capacity when Replacing the existing battery with one that has fewer number of plates the same size?
It is important to replace the battery with one of the same amperage. The number of plates do not matter. If you replace your battery with one of lower amperage, it will not last nearly as long.

How do you install single phase auto transformer?
Before installing the auto transformer there are a few things that have to be looked into. First the transformer has to be sized to the load that you have. Once the secondary load is determined the amperage of the load has to be determined to find the wire size for the secondary feeders. One the secondary has been calculated the primary feeders have to be ampacity calculated as to sizing. This will be determined by the voltage ratio between the two voltages that you will be working with. The higher the primary voltage the smaller the wire size due to the lower amperage. Once the amperage of the primary feeders are determined then the breaker for the supply can be found. Remember that transformer feeders have to be rated at 125% capacity of the primary current. Keeping the above in mind, if you re ask the question with all of the values in place, instruction on how to put it all together will be forth coming from this answerer.
