Yes, a 9v battery can be dangerous if mishandled or ingested, as it can cause burns or internal injuries. Ingesting a 9v battery can also lead to serious health complications or even death. It is important to handle and store batteries properly to avoid accidents.
Using a 9V 600mA power supply to replace a 9V 1A power supply may not provide enough current to power the device properly. It is important to match the voltage and exceed the current requirements of the device to avoid damage or malfunction.
Not enough information - it depends on the cell or battery. Power = voltage x current. Energy = power x time = voltage x current x time. The amount of current each of these can provide, and how long it can provide it, would depend on their corresponding sizes, and constructional details (such as, what materials they are made of). However, in many cases a battery with a larger voltage will also be bigger, and provide more total energy.
Negative voltage is just a voltage that instead of being positive is negative. If you think of a voltage as a large amount of water in a reservoir, with a pipe connecting it to a basin below, the voltage is the movement of the water from the reservoir to the basin. However, a negative voltage is more like a suction from the basin back up to the reservoir. Anyway, if you connect the black ( - ) lead of a 9V battery to the black lead of another 9V battery, then the connection between the two black wires is at 0V, or Ground, and one of the batteries' leads will be at +9V, and the other will be at -9V. Negative voltages are only really used in complex circuits, such as ones that contain Operational Amplifiers, and in general doesn't matter in hobby and simple electronics.
A 9V CD player operating through a 12-volt-to-9-volt converter plugged into the WAGAN 12V power supply will use less power because the converter will efficiently step down the voltage to match the CD player's requirements, resulting in less energy loss compared to using an inverter to power the CD player directly at 9V.
A resistance of 3 ohms connected between the terminals of a 9-volt battery will result in a current of 3 Amperes. If the battery is one of those little ones with snaps on top, it may be able to produce 3 amperes of current for about 3 seconds before it rolls over and totally dies.
no
you better not. you need a 9V regulator for this, not a resistor!
no
No.
You can buy 9V batteries from almost any supermarket
A car battery has six cells each producing two volts. A 9v alkaline battery has six cells each producing 1.5 volts. There are some obvious differences, like that a car battery can put out hundreds of amps and a 9v alkaline can only put out hundreds of milliamps, a 9v battery weighs 45 grams versus 45 pounds for a car battery, and so on.
very
yes the invert mini takes 1 9v battery. it is in the grip frame. you should get a 9v with the gun/
Current I = V/R V = 9V R = 100ohm I = 9V/100ohm = 90mA
No.
The answer is no.
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.
