The equation V/R=A (where V=voltage-volts, R=Resistance-ohms, and A=Amperes-amp) can be used to figure the amps at a certain voltage and resistance.
If You short circuit a 9 volt battery (cross the two terminals) with a paperclip, then the voltage will be 9 volts and the resistance will be in the range of .1 ohms.
What else can I help you with?
What is stronger 1.5 volt batter or a 9 volt battery?
A 9 volt battery is stronger than a 1.5 volt battery because it has a higher voltage. The higher voltage allows the 9 volt battery to power more demanding devices and last longer than a 1.5 volt battery.
How many watts in a 9 volt battery?
The question should be how many amp-hours in a battery. In a small batt. like a 9V, this is measured in milli-amp hours (mAh), with 0.5 amp hours equaling 500 mAh. This means the battery could power a 0.5 amp load for 1 hour. Data I have seen shows the best alkaline 9V being between .3 and .5 amp-hour (300 to 500 mAh).
What happens to the current in a circuit if a 1.5 volt battery is removed and is replaced by a 9 volt battery?
If a 1.5 volt battery is replaced by a 9 volt battery in a circuit, the current flowing through the circuit will likely increase. This is because the higher voltage of the 9 volt battery will provide more electromotive force, pushing more current through the circuit, assuming the resistance remains the same.
9 volt power supply in place of a 10 volt?
Probably ok if the new supply can produce the required amount of current in amps.
What is maximum current of 9 volt dc battry?
The maximum current capacity of a 9-volt DC battery will depend on the specific type and size of the battery. However, for a typical alkaline 9-volt battery, the maximum current output can range from around 500mA to 1000mA. It is important to check the specifications provided by the manufacturer for the exact current rating of the specific battery model.
How many amps are in a 9volt battery?
It varies from one 9 volt battery model to another. The typical Alkaline 9 volt battery you find in many toys and smoke detectors has 565 mAh (Milliampere Hours) of power. A Zinc Carbon model has 400 mAh. A Lithium has 1200 mAh. There are 1,000 mili amps in 1 amp.
How much power is generated when a 9 volt battery produces a current of 5 amps?
45 Watts
What is stronger 1.5 volt batter or a 9 volt battery?
A 9 volt battery is stronger than a 1.5 volt battery because it has a higher voltage. The higher voltage allows the 9 volt battery to power more demanding devices and last longer than a 1.5 volt battery.
Is 9 amp drill as powerful as 14 volt?
Your question is similar to: "Is an apple more powerful than an orange?" You are comparing two different parameters. Electric Power = Volts multiplied by Amperes = Volt-Amps. To know which drill is more powerful, you need to compare the Volt-Amps of each drill with the other one. If the battery voltage is the same for both drills (it probably is not), then the one with the highest motor current rating SHOULD be the most powerful. However, manufacturers tend to fudge some on their ratings. When they say "This is a 9 Amp drill", often it is not clear or not defined what they mean. Is the battery rated for a 9 Amp output, or is the motor rated to use 9 Amps maximum, or 9 Amps average, or are the wires running from the battery to the motor rated for 9 Amps? You see what I mean. Electric power cannot be measured in Amps or in Volts, but must be a combination of the two (Volt-Amps, or Watts, or Horsepower, or some known and well-defined power quantity).
What is stronger a 1 amp battery charger or a 9v battery?
You cannot compare these two totally different things. As far as amperage the charger puts out more amps if it is an auto battery charger and also puts out 12 volts. If you are talking about a 9 volt battery charger then the battery may or may not be more powerful, it depends on how many mii-amps the charger is putting out.
Can you use a 3 volt charger for a 9 volt battery?
No
Can you use a 6 volt charger for a 9 volt battery?
No, the battery will be overcharged and battery damage will occur if it is done.
Is a lead acid car battery the same as a 9 volt alkaline battery?
No, a lead acid battery is a wet cell battery and a 9 volt alkaline battery is a dry cell battery.
What Happens if a 9 volt battery touches another 9 volt battery?
It heats up very hot and may explode.
Two resistors are connected in series to a 9 volt battery. The larger resistor provides twice as many ohms resistance as the smaller one. The current through the circuit is 3 amps. What is the resista?

Can a 9 volt charger be used to charge a 7.2 volt battery?
no
How fat is a 9 volt battery?
1.3cm
