Ammeter The meter uses for measuring the current is known as the ammeter. The current is the flow of electrons whose unit is ampere. Hence the instrument which measures the flows of current in ampere is known as ampere meter or ammeter. The ideal ammeter has zero internal resistance. But practically the ammeter has small internal resistance. The measuring range of the ammeter depends on the value of resistance. The capital alphabet A represents the ammeter in the circuit. By the current, the ammeter categorises into two types. AC ammeter DC ammeter Like share and support 🙏 😍

A MOSFET (metal-oxide-semiconductor field-effect transistor) is a type of field-effect transistor (FET) that uses a metal-oxide gate electrode to control the flow of electrons between the source and drain. MOSFETs are commonly used in many different types of electronic circuits and devices, including computers, smartphones, and other electronic devices. 👉🏻MOSFETs are known for their high switching speed, low power consumption, and high input impedance. They can be used as switches, amplifiers, or to control the flow of current in a circuit. MOSFETs are typically classified as either n-channel or p-channel, depending on the type of semiconductor material used. 👉🏻MOSFETs are widely used in many applications due to their versatility and high performance. They are often preferred over other types of transistors, such as bipolar junction transistors (BJTs), due to their low power consumption and high switching speed. Like share and support 🙏😍😍👍👍

Basic formulas in electronics that everyone should know: 👉🏻Ohm's law: This is the fundamental relationship between electric current, voltage, and resistance. It states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to its resistance. Mathematically, it is expressed as I = V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms. 👉🏻Kirchhoff's current law: This law states that the sum of the currents entering a junction in a circuit must be equal to the sum of the currents leaving that junction. Mathematically, it is expressed as the sum of all the currents entering a junction equals the sum of all the currents leaving that junction. 👉🏻Kirchhoff's voltage law: This law states that the sum of the voltage drops in a closed loop must equal the sum of the voltage rises in that loop. Mathematically, it is expressed as the sum of all the voltage drops around a closed loop equals the sum of all the voltage rises around that loop. 👉🏻Power formula: This formula relates the power dissipated in a circuit to the voltage and current flowing through it. It states that the power P in watts is equal to the product of the voltage V in volts and the current I in amperes. Mathematically, it is expressed as P = VI. 👉🏻Capacitance formula: This formula relates the capacitance C of a capacitor to its physical dimensions and the type of dielectric material used. It states that the capacitance is equal to the ratio of the charge Q stored on the capacitor to the voltage V across it. Mathematically, it is expressed as C = Q/V. 🙏👉 Support and share the post for more helpful information 😍😍👉👉
