Resistor in Series & Parallel
Resistors in Series
The same current flows through each resistor one after another.
Total resistance is the sum: R_total = R1 + R2 + R3 + …
The voltage from the battery is divided across the resistors.
Example: Two 10 Ω resistors in series → R_total = 20 Ω
Resistors in Parallel
Each resistor is...
Ohms Law
Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant.
Mathematically, this current-voltage relationship is written as,
Symptoms and Causes of Chronic Hives
Symptoms of Chronic Hives
Chronic hives, also known as chronic idiopathic urticaria, are characterized by red, itchy, raised welts on the skin, often called wheals. These welts can vary in size, appear anywhere on the body, and typically last more than six weeks, occurring at least twice weekly. The itching...
Understanding Chronic Hives
Chronic Hives (Chronic Idiopathic Urticaria)Chronic hives, or chronic idiopathic urticaria, are red, itchy welts on the skin that persist for over six weeks, often appearing at least twice weekly. These welts, also known as wheals, may last for months or years, and their cause is frequently unknown. People with...

Semiconductor
A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator. It can conduct electricity under certain conditions, such as when energy is applied, making it essential for electronic devices. Silicon is the most commonly used semiconductor. Semiconductors are the foundation of modern...
Series – Parallel Circuit
Series Circuit:
In a series circuit, components (e.g., bulbs) are connected end-to-end in a single path. If one component fails, the entire circuit breaks, and all components stop working.
Parallel Circuit:
In a parallel circuit, components are connected across multiple paths. If one component fails, the others continue to work because the...
Alternating Current
Alternating current (AC) is a type of electric current where the flow of electrons, or charge carriers, periodically changes direction. Unlike direct current (DC), where electrons flow in a single, constant direction, AC reverses its direction at regular intervals multiple times per second.
In simpler terms, during one cycle, the...
