How Resistors Work
A resistor reduces current by converting electrical energy into heat. Its resistance, measured in ohms (Ξ©), determines how much it restricts the flow of current. The higher the resistance, the lower the current flow.

Types of Resistors
1) Fixed Resistors: Common types include:
Carbon Film: Cost-effective, general-purpose.
Metal Film: Precision applications, low noise.
Wire-Wound: High power handling.
2) Variable Resistors (Potentiometers): Adjustable resistance, often used for volume control or sensor calibration.

Key Facts About Resistors
Color Code: Resistors use a band system to indicate their resistance. Learn the color code: BBROYGBVGW (Black, Brown, Red...White).
Power Rating: Measured in watts (W), it indicates how much heat the resistor can safely dissipate.
Tolerances: Resistors have a percentage tolerance (e.g., Β±1%) that defines how close their actual resistance is to the labeled value.

Quick Tips for Using Resistors
Always calculate the required resistance value using Ohm's Law: R=V/I.
When in doubt, opt for a higher power rating to avoid overheating.
Combine resistors in series or parallel to achieve desired resistance values.

π Capacitors: The Energy Storage Champions
Capacitors are essential components in electronics that store and release electrical energy in a circuit. They act as mini energy reservoirs, balancing voltage and smoothing out power fluctuations.
How Capacitors Work
A capacitor consists of two conductive plates separated by an insulating material called a dielectric. When voltage is applied, it stores energy as an electric field. The amount of energy it can hold depends on its capacitance, measured in farads (F).
Types of Capacitors
1) Electrolytic Capacitors:
- High capacitance.
- Used for filtering and power supply stabilization.
2) Ceramic Capacitors:
- Low capacitance.
- Ideal for high-frequency circuits and decoupling noise.
3) Film Capacitors:
- Stable and durable.
- Used in precision applications.
4) Supercapacitors:
- Extremely high capacitance.
- Used for energy storage in renewable energy systems.
Applications in Robotics
- Power Filtering: Smoothens out voltage fluctuations to protect components.
- Energy Storage: Provides short bursts of energy for motors or actuators.
- Signal Processing: Removes unwanted noise from signals.
Key Facts About Capacitors
- Polarity: Electrolytic capacitors have polarity (+/-), while ceramic ones are non-polar. Always connect them correctly to avoid damage!
- Voltage Rating: Never exceed the capacitor's voltage rating. A higher margin (e.g., 20%) is always safer.
- Capacitor Charging: Capacitors charge and discharge exponentially, making them useful for timing applications.
Quick Tips for Using Capacitors
- Always choose a voltage rating higher than your circuit's operating voltage.
- Use ceramic capacitors near microcontrollers to suppress high-frequency noise.
- For power circuits, combine electrolytic (bulk storage) and ceramic capacitors (noise filtering).
