yes there is a need for cost effective power supply like solar energy
Need more information - a typical regulated power supply would include dozens of resistors, each for one of several different reasons. Which resistor are you asking about?
Obtain a power supply that has the correct output voltage that you need.
When your computer will not power on. When the cooling fan of the power supply has failed. When the amount of hardware in use in your case exceeds the power capability of your power supply.
To add more memory cards you do not need a larger power supply. To add more hard drives for more memory storage space you might need to increase power supply.
to give power in the appliances,that we need in power.
continuous
The power adapter need 230v, 50Hz supply
Power supply is dictated by your motherboard, simply get the power supply which matches the motherboards pin configuration.
No No No. If your supply can give .2A, and you need 2 Amps, your supply's not going to cut it.
Yes, you can use a 6-volt DC power supply to recharge a 6-volt DC battery, but you need to ensure that the power supply can provide the appropriate current and is regulated to prevent overcharging. However, it's generally better to use a dedicated battery charger designed for that specific battery type to ensure safe and effective charging. Additionally, if the battery is a lead-acid type, it may require a higher voltage during charging to ensure proper charging. Always check the manufacturer's specifications for the best results.
You need to make sure you buy a power supply that is rated for your motherboard. Common ratings are 350w, 400w and 500w.
You need to convert the voltage if your appliance requires less voltage than you power supply. example: appliances is 110V and power supply is 220V.
