We have introduces Keyboard Shortcuts for DCACLab so that you can use the online circuit simulator more easily than before.

Keyboard shortcut to flip the components in DCACLab

how to flip components in dcaclab

In order to flip the component you have to click on it. You will get to know that the element is selected when the gear sign appears. Tap F Key to flip the selected component.

Note : If the component is not supposed to flip it will vibrate for an instant.

Keyboard shortcuts to rotate the components in DCACLab

Rotation can be done in two ways. Press R key to rotate the selected component clockwise direction and press Shift + R Key for anticlockwise direction.

Note : If the component is not supposed to rotate it will vibrate for an instant.

Keyboard shortcuts for Undo and Redo steps in DCACLab

While working with your circuit you might need to go back or forth the steps. There was a button for undo and redo at the top of the board.

However, For the ease of your experience we have introduced the shortcut keys that is Ctrl + Z for UNDO (Get back to the previous step) and Shift + Ctrl + Z for Redo (Get back to the next step which you came back from).

Note : Once you took certain action after undo you can’t get back to that step again.

How to change the Color of Components in DCACLab

There are certain components such as Lamp bulb, LED and the wires which we can change the color of.

How to change the Color of LED in DCACLab

LED in dcaclab

#Step 1 : Select an LED which you want to change the color of and chick on the color button appears beside the selected LED.

#Step 3 : You will see the LED of the color which you’ve had selected.

Note : The threshold voltage for the LED to light up will be effected as the corresponding voltage you select.

How to change the Color of Lamp Bulb in DCACLab

Step 3 : Click on the desired color from the option appears in step 2, the bulb will be converted into the color which you have had selected and will glow of the same color.

How to change the Color of Wires in DCACLab

Step 2 : A strip of colors will appear after you click on the color button in the step 1. Click on the selected color in order to change the color of the selected wire.

Step 3 : The color of the wire will be changed to your desired color.

Customizing the color of wires helps us to define the different part and section of the circuits easily and make it more interactive for others specially if we are sharing the idea with others.

Try the above shortcuts in DCACLab and let us know about your experience, We will be glad to hear from you ! 🙂

Updates for LED in DCACLAB

Updates for LED in DCACLAB

We keep introducing the new updates in the DCACLAB in order to provide you the more real like experience in the virtual lab.

Maximum Current for LED

In this update the LEDs will blow if the current exceeds above 20mA or 0.02A. You will have to apply a suitable value of resistance in order to use the LED just similar to real life circuits.

Below is the example of three circuits, Circuit A which has no resistance, Circuit B with resistor that has a value below then required and Circuit C with resistor that has a sufficient resistance.

Testing LED with different resistances

  • In the Circuit A there is no resistance connected in series to the LED which causes the flow of current up to 35.93A which is far more the required current for an LED to operate. Hence, the LED blows.
  • In the Circuit B there is a resistance of 11 Ω connected in series to the LED. In this condition there is the current of 0.051A flows through the LED which is more than the maximum of 0.02A which causes the LED to blow.
  • In the Circuit C there is the resistance of 22 Ω is connected in series to the LED. In this condition there is a current of 0.019A flows through the LED. Since the current is below 0.02A the LED is intact and works fine.

LED Color and its Corresponding Threshold Voltages

 

With a recent update in the DCACLAB a feature in LED was introduced in which you select the color of the LED and its corresponding threshold voltage takes into effect.

Below is the list of the color and its threshold or forward voltage which you will find while switching the colors of the LED.

  Color Name Threshold or Forward voltage (Vf @ 20ma)
Ultra Red 1.8
Super Red 2.2
Super Orange 2.2
Orange 2.1
 Yellow 2.1
Cool White 3.6
Super Lime Yellow 2.0
Super Lime Green 2.0
Pure Green 2.1
Aqua Green 3.5
Blue Green 3.5
Super Blue 3.6
Ultra Blue 3.8
