Electronics and Robotics Basics

What is Ohm's Law and how is it expressed mathematically?

• V = R / I

• I = V + R

• R = V - I

• Ohm's Law is expressed as V = I * R.

What are the three basic components of a circuit?

• Battery, resistor, switch

• Power source, load, conductive path

• Voltage source, capacitor, diode

• Generator, transformer, relay

What is the function of a resistor in a circuit?

• To increase current flow in a circuit.

• To convert electrical energy into heat.

• To limit current and control voltage in a circuit.

• To store electrical energy for later use.

Name two types of sensors commonly used in robotics.

• Pressure sensors

• Temperature sensors

• Ultrasonic sensors, Infrared sensors

• Magnetic sensors

What is the purpose of a microcontroller in a robot?

• To act as a physical structure for the robot.

• To store data for the robot's sensors.

• To provide power to the robot's motors.

• The purpose of a microcontroller in a robot is to control its operations and process inputs to perform tasks.

Which programming language is often used for Arduino programming?

• Python

• JavaScript

• C++

• Java

What is the difference between analog and digital sensors?

• Analog sensors provide continuous signals, while digital sensors provide discrete signals.

• Analog sensors can only measure temperature.

• Digital sensors are used exclusively in cameras.

• Analog sensors are faster than digital sensors.

How do you define a loop in programming for robotics?

• A loop is a control structure that executes a sequence of instructions repeatedly based on a condition.

• A loop is a method for storing data in memory.

• A loop is a single instruction executed once.

• A loop is a type of robot sensor.

What is the role of a motor in a robotic system?

• To store energy for the robot's operations.

• The role of a motor in a robotic system is to provide movement and control.

• To power the sensors in the robotic system.

• To act as a communication device between components.

What is a breadboard and how is it used in circuit design?

• A breadboard is a type of electronic component that requires soldering.

• A breadboard is a software tool for coding applications.

• A breadboard is a type of bread used in cooking.

• A breadboard is a tool for prototyping electronic circuits, allowing components to be connected without soldering.
