Which uses less power a 9v CD player operating off of a WAGAN 12 v power supply inverter or a 9v CD player operating off a 12-volt-to-9-volt converter plugged to the WAGAN 12v power supply?
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.
Can a 9v battery kill you if mishandled or ingested?
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.
What is meant by negative voltage and how it creates?
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.
Can iron be made into a permanent magnet?
take a block of iron and then coil some wire around it, then attatch it to a power source and your iron block will act as a magnet due to the magnetic field produced by the coil. the more coils you have, the stronger the magnet and vice versa. in order to create a strong magnet you'll need to produce around 8 or 9V of electricity, so a standard 9V battery should work fine.
How much current is in a circuit that includes a 9 volt battery and a bulb with a resistance of 12 ohms?
The current depends on the total effecvtive resistance of everything connectedacross the battery.If the bulb is the only component there, then the current is E/R = 9/12 = 0.75 amperes.
Can you use a 9V 600mA adapter on a 9V 400ma scanner?
You can use any 9v adapter as long as the output amperage is rated higher than the amperage rating of your appliance so yes a 600ma adapter can be used to power a 500ma or 400ma appliance
What adapter has more power the 9v 600ma or the 9v 800ma?
The capacity of the 800 mA adapter is 200 mA larger than the 600 mA adapter.
Can you use a 9v 600Ma adaptor to power a 9v 300Ma appliance?
I think you mean to ask if one can use a 9v 600mA adapter to power a 9v 300mA appliance. Yes, you can do that. A 9v 600mA adapter will deliver 9v at up to 600mA. A mA is one milli amp, or one thousandth of an amp. 300mA is 300 thousandth of an amp, 300/1000 or 0.3 amps. 600mA is 600 thousandth of an amp, 600/1000 or 0.6 amps, and is twice the current of 300mA.
Can you use a 9v-1a power supply when it calls for 9v-2000ma?
Unfortunately no, if the device calls for 2000ma you will need a 2A (amp) power supply to adequately power it.
Is it safe to use a 5v 1200ma router power adapter instead 9v 600ma adapter the original one for a longer period because everything works fine for now?
no .never
Can a 9V 1A replace a 6V 300ma power cord?
No, a 9V 1A power supply cannot replace a 6V 300mA power cord. The voltage of the replacement power supply is higher than the original required voltage, which could damage the device. Additionally, the current rating of the replacement is sufficient, but it’s essential to use a power supply that matches both the voltage and current specifications of the device. Always adhere to the manufacturer's requirements for voltage and current to ensure safe and proper operation.
Can you use a 9v dc 1000ma adaptor for a device that has 'power input' of 15v dc 800ma?
A: Disregarding the fact of different voltages there is the power to be concerned 9v x 1A = 9W, 15V X .8 = 12W. THE DEVICE WILL BE UNDER POWER.
Can 9V 1A adapter be used for 12V 1A speakers?
No. If it works at all, it will be underpowered, and possibly damage the speakers. To power 12V speakers, you have to have an adapter with EXACTLY 12V (no more, no less), and at least 1A. You could hook up a 12V 4A adapter if you wanted to, your speakers would just only draw 1A of power. Make sure you use a 12V adapter though!!
Can 9V 1A router adaptor be used for 12V router adaptor?
No, a 9V 1A router adapter cannot be used for a 12V router. The voltage rating is critical, and using a lower voltage can lead to insufficient power supply, potentially causing the router to malfunction. Additionally, the 1A current rating may not meet the power requirements of the 12V router, risking damage to the device. Always use an adapter that matches the specified voltage and current ratings for optimal performance and safety.
Can you use a 6V 2amp adapter on a 6V 600mA device?
No. You need to use the exact battery charger for the battery specified by the manufacturer, in order to achieve the correct charge cutoff point. In particular NiCad and similar batteries detect full charge by detecting the knee point in voltage per unit time given a specific charge current. Using the wrong charger could result in overcharge which will damage the battery.
Can you use a 9v 300mA adapter on a 9v 200mA device?
No. The adaptor will overheat.
Can you use a 9v to replace a 24v adapter?
No, you cannot use a 9V adapter to replace a 24V adapter, as the voltage difference is significant. Devices designed to operate at 24V require that specific voltage for proper functionality and safety. Using a lower voltage can lead to insufficient power, potential malfunction, or damage to the device. Always use the specified voltage rating for your equipment to ensure optimal performance.
