What Resistor do you need for a 5 watt 1.5 volt alkaline battery?

in terms of Direct current, P=IV. Another form is P=V^2/R. If you are to connect only a single resistor directly to a 1.5 volt battery, you will need a resistor of size 0.45 ohms. Notice though that this is a current draw of about 3.3A. At the typical 2700mAhour rating of AA size battery, it would last (in an ideal world) about 49 min. You will also need some rather large gauge wire to prevent the 3.3A from burning up your wire.

Is a D battery the same as LR20?
Yes. The LR-20 is a D-sized 1.5-volt alkaline battery. The battery number for Duracell is MN1300.
Can you charge a 1.5 volt battery with a 5 volt power supply?
A: YES you can provided that the current is limited as specified by the manufacturer.. In other words you will need a limiting resistor of the right size.
Can you charge a 6 volt battery from a 12 volt source?
The simple answer is NO. Why not use a simple 6 volt power suppy from some junked piece of audio or telephone equipment, Just watch the polatiy when you make your connections. Using 12V on a 6V battery can fry your battery but not the otherway around.
Can you charge a 6 volt battery with a 12 volt battery charger on slow 2amp charge?
No.
What is a 3 volt battery?
A 3 volt battery is a battery that produces 3 volts. Many watch batteries produce 3 volts.
Is a lead acid car battery the same as a 9 volt alkaline battery?
No, a lead acid battery is a wet cell battery and a 9 volt alkaline battery is a dry cell battery.
How many volt does a AAA battery have?

Cost of 9 volt alkaline battery?
$1.000.000.000 hahahaha noob
Is a D battery the same as LR20?
Yes. The LR-20 is a D-sized 1.5-volt alkaline battery. The battery number for Duracell is MN1300.
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
Using an LED and a nine volt battery what resistor should you use?
34Kohms
Can you charge a 1.5 volt battery with a 5 volt power supply?
A: YES you can provided that the current is limited as specified by the manufacturer.. In other words you will need a limiting resistor of the right size.
What is the resistor of 18 ohms when connected to a 9v battery?
Even though it is connected to a 9 volt source, it is still a resistor.
Please HELP How do you connect a small LED light to a 3 volt watch battery with the battery one and a half feet away?
Try wires. You will also need a resistor. You also need to know that a watch battery is not rated to carry the current load of a typical LED.
How do you power a 3 volt DC motor with a 12 volt battery?
you would have to put some type of resistor in the circuit with the motor...the resistor would have to be in series with the motor and would have to be of a high enough value to lower the voltage by 9 volts....There is a formula for working this out but you would need the amperage of the motor to figure this....
