Can I use a 9 Volt 1 Amp power adaptor in place of a 5 volt 1.2 Amp adaptor?
No, the voltage of the replacement adapter must always be IDENTICAL to the original adapter and the current of the replacement adapter must be the same or larger than the original adapter.
Trying to use a 9 Volt adapter to replace a 5 Volt adapter will almost certainly completely destroy the device the moment you plug it in.
You did not say whether the adapters provided AC or DC or the polarity if DC. Either way both the replacement adapter and the original adapter must be IDENTICAL in this respect.
What is the number of turns in primary and secondary coil for 12 volt battery charger with 220 volt power supply?
Yes, a 9 volt 1600 mA AC adapter can be substituted for a 9 volt 300 mA adapter. The mA number represents the highest allowable current to be drawn from the adaptor. The adaptor that you want to replace has only 300 mA maximum capacity. The new adaptor has five time the capacity of the old one which means that devices that draw up to 1600 mA can be connected to it. Depends on what…
it depends how the batteries are connected. if you put the batteries both in positive side up you probably have a 1.5 volt system. if you put one battery positive side up and one down you probably have a 3 volt system. Check to make sure before you connect anything because you can damage the the water pump by connecting it to the wrong voltage or by reversing polarity. if its a 1.5 volt system…
What is the amount of power consumed by a 60 watt 220 volt lamp when it is connected across 110 volt supply?
Volt-Amp is apparent power, in direct current Volt x Amps = power with unit of Watt. For Alternate Current Volt-Amp is generally different from real power because the power supply in wave form and might be out of phase and portion of energy is not usable. Volt-Amp is always higher or equal to real power in AC.
Sure you can. But consider what could happen if you did. If precision of time or speed was built into this 6-volt system, a 12-volt battery will make it work faster until something shorts or burns out. If you need more lasting power for the 6 volt system, you should consider putting two 6-volt batteries in parallel to power your 6-volt system.
