Usually you'll need 100ohm resistor for each led. In this kind of setting, you will get the LED intensity nonuniform because of its differences due tolerance value. the best thing is to use LED driver IC. Another benefit of using LED driver is, you can mix red led with other color.
Now, if we wanted to connect a red LED with a forward voltage of 1.8V and a current of 20mA directly to the transformer output then use the following equation:
R=V/I = 9 / 0.02 = 450 Ohms.
You could use 470 ohms from the E12 resistor series.

Which resistor is connect 1.5 volt led to series 220v ac?
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.
What is a protective resistor?
The protecting resistor is put in series with the LED so that you have a voltage divider - the supply voltage is split across the LED ( max 0.6v) and the remainder across the protecting resistor. So if your supply is 6volts, 5.4v will be across the resistor,
Which way does LED go in a circuit?
series
What the role of a resistor in an led circuit?
a resister is to RESIST current flow....if the LED gets the full effect of the power supply, the LED will immediately blow out.
A component used to protect an led in a circuit?
you could use a current limiting diode such as a Zenner, or a current limiting resistor in series with the LED
How can I connect multiple LED strips to one power source?
You can connect multiple LED strips to one power source by using a power supply with enough voltage and current capacity to support all the strips. You can either connect the strips in parallel or use a distribution block to connect them in series. Make sure to calculate the total power consumption of all the strips to ensure the power supply can handle it.
How can I connect LED strip lights to a power supply?
To connect LED strip lights to a power supply, first determine the voltage and current requirements of the LED strip lights. Then, match these requirements with a compatible power supply. Next, cut the LED strip lights to the desired length and strip the ends of the wires. Connect the positive () and negative (-) wires of the LED strip lights to the corresponding terminals on the power supply. Finally, plug in the power supply and test the LED strip lights to ensure they are working properly.
Which resistor is connect 1.5 volt led to series 220v ac?
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.
How can I replace tube lights with LED lights?
To replace tube lights with LED lights, follow these steps: Turn off the power supply to the tube lights. Remove the existing tube lights from their fixtures. Install LED light fixtures in place of the tube lights. Connect the wiring of the LED lights to the power supply. Turn on the power supply and test the LED lights to ensure they are working properly.
How to wire LED lights in series for optimal performance?
To wire LED lights in series for optimal performance, connect the positive terminal of one LED to the negative terminal of the next LED. Repeat this pattern for all the LEDs in the series. Make sure to use the appropriate resistor to regulate the current and prevent damage to the LEDs.
How do you hook up 12 L E Ds to 9 volt battery?
Either 4 parallel rows of three LED's in series or 3 rows of four series coupled LED's (make sure to connect them correctly (+ to - to + to - ...))
What is a protective resistor?
The protecting resistor is put in series with the LED so that you have a voltage divider - the supply voltage is split across the LED ( max 0.6v) and the remainder across the protecting resistor. So if your supply is 6volts, 5.4v will be across the resistor,
How can I connect multiple LED strips together?
To connect multiple LED strips together, you can use soldering or connectors. Cut the strips to desired lengths, solder wires between the strips, or use connectors to link them. Ensure proper polarity and power supply to avoid damage.
How can I connect LED strips to create a cohesive lighting design in my space?
To connect LED strips for a cohesive lighting design, start by planning the layout and placement of the strips. Ensure all strips are compatible and connect them in series or parallel using connectors or soldering. Use a controller to adjust colors and brightness for a unified look.
How can I connect LED lights to create a lighting display?
To connect LED lights for a lighting display, you will need to first determine the power source and voltage requirements of the LEDs. Then, connect the LEDs in parallel or series circuits using appropriate resistors to control the current. Finally, use a controller or switch to control the lighting effects and patterns of the display.
