Is 24 volt DC is equal to -48 Volt DC?

No. The value and polarity are different.


How do you change 3 volt dc into 4.5 volt dc?

With an invertor/rectifier or voltage multiplier.


Does 48 volt dcwork with 100watt ac bulb?

No, a 48-volt DC power supply cannot directly power a 100-watt AC bulb. AC bulbs are designed to operate on alternating current, typically at standard voltages like 120V or 240V, and require an AC waveform. To use a 48-volt DC supply, you would need a compatible DC bulb or a DC-AC inverter to convert the DC to AC at the required voltage and frequency.

What appliance uses a 48 or 72 volt DC motor?

Electric bicycles (e-bikes) often use 48 or 72 volt DC motors for their propulsion systems. These voltage levels provide a good balance between power and efficiency, allowing for higher speeds and improved performance. Additionally, some electric scooters and certain types of electric vehicles may also utilize these voltage ranges for their motors.


Why we used ac volt in supply line instead of dc volt?

AC voltage is more sufficient than DC voltage. Moreover, an AC transformer can be developed but DC voltage will make it harder. Without a transformer, we cannot turn the high and low voltaged into each-other.

Why Base Transceiver Station equipments require negative 48 volt DC to function properly why not positive?

it has two reasons.one is to prevent corosion due to the elecrtolitic effect and the other is to protect operator from the line voltage.. it has two reasons.one is to prevent corosion due to the elecrtolitic effect and the other is to protect operator from the line voltage..


Can you add DC voltage in parallel?

Connecting 12 volt DC batteries in parallel will increase amperage available, but voltage will remain 12 volts.


Will a 12 volt light plug into a standard wall outlet?

No, it will cause the bulb to blow. A 12 volt light is DC voltage and your home outlet is AC voltage.


How can you power your CB at home to a standard wall outlet?

Get a 120 volt ac to 12volt dc power supply. you plug them into a house outlet and it converts120 house voltage to 12 volt dc , some have regulators on them and you can turn the dc voltage up and down on them. make sure you set your device to the proper voltage before turning on.
