Circuit analysis using breadboard and TinkerCad

Look at the breadboard in the picture. Which of the following rows/columns of holes are electrically connected with each other?

• A5, B5, C5, D5, E5

• A5, B5, C5, D5, E5 connected with f5, g5, h5, i5, j5

• • "-" row and "+" row

• f1, f2, f3, f4, f5

Look at the picture. Is that correct placement of a resistor?

• 
• Yes, current will flow through resistor.

• No, the resistor is placed incorrectly. Current will bypass it.

• 

Look at the image. Can we wire the resistor like this? Find the correct explanation.

• 
• No, it is now allowed. Current won't flow via green wire.

• No, we cannot. Resistor placed on the same row as the green wire - this row is already connected.

• Yes, we can. This is the best wiring. The shortest and the most optimal way to connect 2 holes.

Which circuit is correctly wired?

• 
• 
• 
• 

Select correct circuit.

• 
• 
• 
• 

On which circuit push-button will turn on and turn off the LED?

• 
• 
• 
• 

Select the most optimal and correct wiring (with minimum wires):

• 
• 
• 
• 

Choose the correct current path after pressing the button.

• 
• 
• 
• 

Which LED or LEDs will not light up after starting simulation? (LEDs are labeled 1, 2 and 3 on the image)

• 1 and 3

• 2
• 1 and 3

• 3

Select true statement

• Capacitors connected in parallel with increase lighting time of a LED

• We can ignore "-" and "+" labels but then we have to remember which wire gives positive, and which gives negative.

• Breadboard helps us to avoid soldering and quickly check our circuit

• Current is lazy and chooses the path with less resistance
