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 else can I help you with?
Can you use a 16 or 18 volt battery in a 14 volt ryobi cordless drill?
Absolutely not! It is a 14 volt drill. Use a 16 or 18 volt battery will destroy the drill in short order. It will run but not for long.
Will a 14-2 gage wire work for a 240 volt 15 amp breaker?
No. You will need a 14/3 with Ground.
How many kva in 14 amp?
There is appoximately zero kVA in 14amp, .5 volt AC.
Can a 240 volt receptacle go on a 15 amp circut breaker?
In North America you would need two 15 amp breakers to obtain 240 volts. The wire for a 15 amp circuit would be #14 AWG. So to answer the question, yes a 240 volt receptacle can go on a 15 amp circuit.
How long does it take to charge a car battery using 12 volt 4 amp battery charger?
14 hours approx
What type of electrical outlet is required for a device that needs to be plugged into a 50 amp 240 volt plug?
The device requires a NEMA 14-50 outlet, which is a 240-volt, 50-amp outlet commonly used for high-powered appliances like electric stoves or RVs.
Can the neutral line be temporarily blanked out on a dryer outlet so you can use the red and black lines to power up a 240vac 7amp saw?
This is not a good idea because the breaker that is there to protect the drill will be rated at 30 amps. You should use a dedicated outlet for this type of installation. The main materials needed would be a two pole 15 amp breaker, 2 conductor #14 wire and a 240 volt 15 amp receptacle. An adapter box can be made with a dryer cable into a metal 6 x 6 x 4 screw cover metal box. Inside this box will be a 15 amp fuse in a 300 volt rated fuse block. From the fuse block connect the 240 volt 15 amp receptacle that is cut into the screw on lid of the junction box. This will work well for temporary occasions. Make sure if you go this route that a fuse be included to protect the drill from over current faults.
What is the minimum ground wire size for a 20 amp 110 volt circuit?
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.
Can you use a 12 volt adapter on a 15 volt device?
No you shouldn't use a 14 volt 5 amp adapter on a 12 volt 5 amp device unless you know for sure that the 12 volt device has an internal voltage regulator that will lower the voltage to the correct voltage range the device was designed to use. As long as you always take care to check the output voltage with a voltmeter first, to be sure that the voltage from the adapter is regulated, meaning that it does not rise when a lower current in amps is drawn from it, you may be able to use an adapter that gives the right voltage at a higher amp output rating than the device actually takes. (For example, it may be possible to use a 12 volt 7 amp adapter for a 12 volt 5 amp device.)
1 amp current at 14 volts causes a .9 volt drop across a switch. what is the resistance at the switch?
V = I*RIf you solved this for resistance, this means you would have:V/I = RYou set V = .9 volts, I = 1 amp, and solve to get .9 Ohms.
Can you use the ground conductor in a 14 AWG 2 conductor with a ground for the neutral in a 220V 15 amp circuit with less than 50ft run?
yes <<>> No, the ground wire is never to be used as a neutral. In this case if you need a 120 volt circuit from the 220 volt circuit a three wire cable (3C #14) must be installed.
Will a 14 volt charger hurt a 18 volt battery?
Yes, an 18 volt charger can damage a 14 volt battery. This is because the wattage for the battery needs to be equal to the wattage of the charger.
