Depends on the led forward bias threashold, if its a typical led it will be .7 volts so, .7x6=4.2V, so pick a resistor that will drop around 7 volts. What is the current? Then just to V=IR, 7=IR.
How much current? Volts/Amps = Ohms. In your case Volts = 1.5
No
You give it more volts and it will burn out something!!
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
A DC 12 power source refers to a direct current electrical supply that operates at 12 volts. It is commonly used in various applications, including automotive systems, consumer electronics, and renewable energy systems like solar panels. Devices powered by a DC 12 source can include LED lighting, small appliances, and computer peripherals. These power sources can come in the form of batteries, power adapters, or power supplies.
If you want to convert 24v AC into 12v Ac, it's simple. Just get a transformer to convert 24 volts into 12 volts. This is called a stepdown transformer. If you want to convert 24v DC into 12v DC, it's more complicated. First you have to change the 24v DC into 24v AC by a switching converter that changes DC into AC. Then you would use a stepdown transformer as in the former example. Once the 24v AC is converted to 12v AC, then you use a rectifier bridge to change the 12v AC into 12v DC.
No.
yes its a dc to dc converter used in trucks to power radios cbs etc the load is important thing to know but that's the thing u nead, step down converter
12 volts DC
12 volts DC.
Yep. It is called an inverter to convert 12 volts to 110 volts AC. Get one that will supply the amp needed for the microwave.
12 volts DC
12 volts DC.
12 volts DC.
dc - the voltage is a constant 12 volts nominally in a normal car battery.
How much current? Volts/Amps = Ohms. In your case Volts = 1.5
To calculate the current (in milliamps), you can use the formula: Current (in mA) = Power (in watts) / Voltage (in volts). In this case, Current = 2 watts / 12 volts = 0.167 amps. To convert this to milliamps, multiply by 1000: 0.167 amps * 1000 = 167 mA. Therefore, there are 167 milliamps in a 12V DC, 2W DC circuit.
