This block starts the program when the green flag is clicked.

“When green flag clicked” block

100

This VEX part connects beams and plates together.

pegs

100

This thing carries electrical current from one component to another.

Wire/conductor

100

This unit measures electrical resistance.

Ohm

100

This component lights up when electricity flows through it.

LED/LIGHT component

200

This Scratch block repeats code a certain number of times.

Repeat block

200

Gears are used to change this.

Speed and torque

200

Red wires are commonly used for this electrical direction.

Positive (+)

200

If voltage increases while resistance stays the same, current does what?

It increases

200

This Snap Circuits component makes sound.

Speaker/Buzzer Module

300

This type of block lets your program make decisions.

If/else block

300

A circuit with a break in the path is called this.

An open curcuit

300

A circuit has 12 V and 4 ohms. What is the current?

3A

400

This loop runs forever unless the program is stopped.

Forever block

400

Triangles are commonly used in robot structures because they are…

The strongest shape/strong and rigid

400

Connecting a battery directly from positive to negative without a resistor or a component creates this.

Short curcuit

400

A circuit has 20 V and 5 A. Find the resistance.

4 Ohms

500

This Scratch block sends a message to start another script.

Broadcast Block.

500

In a series circuit, if one bulb burns out, what happens to the others?

They all go out
