Typically, a 100 ohm resistor is used to connect a 1.5 volt led to a series 220v ac adapter. Many LEDs can be connected into a string using the resistors.

A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source. What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor?
The current would be about 20 volts.
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.
How do you connect two 12 volt batteries into a 24 volt hitachi ex60 excavator?
Connect the two 12 volts batteries in Series. Battery 1 & 2. Connect the negative post (-) of battery 1 to the negative (-) ground cable. Then connect the positive (+) post of battery 1 to the negative (-) post of battery 2. Connect the positive (+) post of battery 2 to the positive (+) cable. You now have 24 volts as the batteries are wired in series.
What are the laws of series and parallel connection?
1.In series connection the total resistance is equal the total number of resistor that was connected in series 2.the current is constant in a series connection 3.in a series connection total voltage is equal the number of of volt per cells
What is cheaper to operate 120v motor or 220v same horsepower?
220 volt will use less energy.
Can a Volt motor run on Volt?
Short answer: No. (unless you like ruining motors) Longer answer: Not really, but there are some motors that can be re-wired so that instead of 440v they will run on 220v. However, this is not that common. Conclusion: Check the motor to see if it is dual-voltage on it's nameplate. If it is, you can re-connect it to work on 220v. If it is NOT a dual-voltage motor, you will absolutely ruin it if you connect it to 220v.
How do you connect six 6-volt cart batteries?
Connect them in series.
How do you connect several 12 volt batteries to make 24 volt?
you only need two 12 volt batteries to make 24 volt. connect them in series
If two bulbs in a series are connect to a battery and the current in the first bulb is found to be 1 ampere then what is the current through the battery?
A circuit with a 2 ohm resistor and a 4 ohm resistor in series with a 12 volt battery will have 2 amps flowing through each resistor. The current is the same in each resistor because they are in series, and a series circuit has constant current throughout.
How do you hook up 4 6volt batteries to get 12 volt?
Connect two 6 volt batteries in series. Connect the other two 6 volt batteries in series. Now connect those 2 pairs you have together in parallel. You will end up with 12 volts.
What is the current in a 12-volt circuit with a 6-ohm resistor connected series?
2 A (amperes)
What should you do to convert a galvano meter into volto meter?
Connect a large but precisely known resistance in series with the galvanometer. For example, if you connect a 1-Megohm resistor in series with it, then the galvanometer will indicate 1 microampere of current when it's connected across a potential difference of 1 volt ... quite a sensitve voltmeter.
How do you connect a 12 volt winch to 24 volt system?
Connect the 12V winch to one battery, assuming the 24V system has two batteries, connected in series.
How do you connect two battery for 24 volts?
Connect two 12 volt batteries in series and you will have 24 volts.
In order for a 30 volt 90 watt lamp to work properly in a 120 volt supply the required series resister in ohm is?
A 30 volt 90 watt lamp has 3 amps going through it. The series resistor also has 3 amps going through it, by Kirchoff's current law. The voltage across the resistor is 90 volts. With 3 amps, that is 30 ohms. (By the way... The resistor must be rated to carry 270 watts. That is a lot of power for a resistor.)
A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source. What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor?
The current would be about 20 volts.
How do I connect a twelve volt car battery to two six volt batteries connected in a series?
connect the 2 six-volt batteries together one terminal each positive to negitive, this will make a 12-volt combination, then you can connect the jumper cables, one side to the 12-volt battery and one side to the two 6-volt terminals, + & -
