How to Measure Voltage, Current, and Resistance in a Circuit
A multimeter is a device specifically designed to measure the voltage drop, resistance, and amperage of electrical current in a circuit.
Although an oscilloscope can be used to measure these parameters, its primary function is to visualize and analyze the…
The Current, Voltage, and Resistance Relationship
Current, voltage, and resistance are the three important electronics concepts that form the foundation of understanding how circuits operate. Current represents the flow of electric charge through a conductor, voltage is the electrical potential difference that drives this flow, and…
Basic Electronic Components in Circuits
As you progress, you’ll start working on projects or circuits that incorporate a variety of electronic components.
To gain more confidence building your circuit, familiarize yourself first with the fundamentals. Start learning the basic components that are commonly used in…
What’s the Difference Between Alternating and Direct Current
In electronics, you’ll be dealing with two types of electricity: Direct Current (DC) and Alternating Current (AC).
If you’re a beginner, you’re probably familiar with AC as the primary form of power distributed in homes and industries, while DC is…
Capacitors in Series and Parallel Explained
A capacitor is a passive two-terminal electronic component that can store electrical charge. But did you know that you can connect multiple capacitors in either parallel or series to meet specific design requirements in electronic circuits?
Before delving into this…
Circuit for Beginners: Resistors in Series and Parallel
In electronics, resistors are components designed to impede the flow of electric current, and how they’re connected in a circuit makes a big difference. There are two main setups: resistors in series and resistors in parallel.
Now why should we…
What is an Inverting Operational Amplifier (Inverting Op amp)
The primary function of an operational amplifier (op-amp) is to amplify voltage signals, and it accomplishes this through a combination of distinctive features.
Picture the op-amp as a highly efficient amplifier with two entrances: the inverting and non-inverting inputs. These…
How to Design a 555 Astable Oscillator Circuit
The 555 timer is an incredibly versatile integrated circuit that finds application in a myriad of electronic circuits. It can be used as three distinct types of oscillators because it has the flexibility to generate a repetitive waveform for different…
Capacitor Charging: Decoding the RC Time Constant
Capacitor charging revolves around the transfer of electrical energy to the capacitor, resulting in an increase in voltage across its terminals.
The figure below shows a capacitor (C) and a resistor (R) connected in series to form an RC Charging…
