The resistance of an ideal voltmeter is considered to be infinite. This characteristic is crucial for the accurate measurement of voltage (potential difference) across two points in a circuit without affecting the circuit itself. Concept of Ideal Voltmeter An ideal voltmeter is a theoretical device that measures the potential difference between two points in a […]

Introduction In physics, equilibrium refers to a balanced state where the net force and net torque acting on a body are zero. This concept helps us understand why objects either remain at rest or move with constant velocity. When studying mechanics, we encounter two primary types of equilibrium based on the motion characteristics of objects.

We all know what happens when we turn on a torch or plug in a fan—the device starts working as soon as we flip the switch. But have you ever wondered why the current starts flowing, and how it relates to the voltage we apply? Let’s break down the relationship between current and voltage using

Acceleration ($a$) is defined as the rate of change of velocity. It tells you how quickly velocity increases or decreases. The question ‘How do you solve for acceleration in physics?’ can be answered briefly as follows: Here, I’ve introduced two formulas—we’ll go through each one step by step, along with a solved example for better

1) The main purpose of the capacitor is to store charge . If an instantanous strong current is to be flown in a circuit,the best way would be to connect the terminals of the circuit to a charge capacitor
2 A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary battery. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed. (This prevents loss of information in volatile memory.)

A LED is a forward biased P-N junction diode which emits visible light when energized.
A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.
