Ohm’s law explains the relationship between voltage, current, and resistance in a circuit.

Where:

V = voltage expressed in Volts

I = current expressed in Amperes or Amps

R = resistance expressed in Ohms (Ω)

 

Ohm’s law is calculated using what formula?   

• V = R / I

• V = I – R

• V = I / R

• V = I x R

What type of circuit is shown in the image?

This type of circuit is when there is a connection between two points that should not be connected directly. For example, when connecting the two terminals of a power supply directly. 

• An open circuit

• A short circuit

• A closed circuit

• An overloaded circuit

Look at the four node lines circled in the breadboard image. These are known as the ______________. 

• power rails

• power banks

• power trains

• power sources

In electronics, a photoresistor is a component that has a variable resistance. Its resistance decreases when the intensity of ________ increases.  

• heat

• water

• sound

• light

In electronics, a _______ removes electrical current from an electrical circuit when the current is too high. The metal wire inside it melts (breaks or blows).  

• transistor

• fuse

• capacitor

• switch

In electronics, what do we call devices that collect and store electricity? They are very useful as they work like rechargeable batteries.

• Fuses

• Transistors

• Capacitors

• Switches

The motion capabilities of a robotic system are defined by its DOF. The DOF for a robotic arm can be identified by the number of joints used to control the position of the arm.

 

In robotics, what does the acronym DOF represent?

• Degrees of freedom

• Degrees of frame

• Degrees of function

• Degrees of field
