by using the step down transformer we can easily reduce the voltage.if we step down means the current(amps) icrease its vry useful for us
AnswerAs Transformers are a.c. machines, you cannot use a transformer for this purpose. You will need to create a voltage dividercircuit -essentially a pair of resistors, of appropriate value, connected in series across the supply.
No, not possible. The charger has to go to higher volts than the battery being charged.
3v
No, the adapter's power output has to be equal to or greater that the current draw of the device.
Current I = V/R V = 9V R = 100ohm I = 9V/100ohm = 90mA
3v
12v dc to 3v dc
3v2 + 9v = 3v (v + 3)
3v2 + 9v = 3v(v + 3)
(8 + 3v)(8 + 3v) or (8 + 3v)2
no, must be 3v
A: No problem but don't expect the power to increase
if you have 12v dc then you can use a 4 ohm resistor
Substituting a 9V DC power supply for a 6V DC supply is generally not advisable, as it can lead to overvoltage conditions that may damage the device designed for 6V operation. Components may overheat or fail, and the device may not function correctly. Always check the specifications of the device to ensure compatibility with the power supply voltage. If a 9V supply is required, consider using a voltage regulator or a suitable step-down converter to safely reduce the voltage to 6V.
conclusion of dc power supply 9V
No. 9 v is only 75% of 12 v.
No. Usually it's a -/+ 10% difference. So, a 9v would need at least 7.2 volts or more
No, it is not recommended to plug a 9V DC power source directly into a 220V outlet. Doing so can damage the device connected to the 9V source and pose a safety hazard. It is important to match the voltage requirements of the device with the power source to avoid potential damage or injury.
