Current Calculator - Calculate Amps - Inch Calculator
Use the current calculator below to calculate amps given the voltage, power, or resistance. In an electrical circuit, current is a measure of the flow of charged particles moving through a conductor. Current is measured in units of amperes (usually referred to as amps).
20.1: Current - Physics LibreTexts
Electric current \(I\) is the rate at which charge flows, given by \[I = \dfrac{\Delta Q}{\Delta t,}\] where \(\Delta Q\) is the amount of charge passing through an area in time \(\Delta t\). The direction of conventional current is taken as the direction in which positive charge moves.
9.2: Electrical Current - Physics LibreTexts
The rate at which the charges flow past a location—that is, the amount of charge per unit time—is known as the electrical current. When charges flow through a medium, the current depends on the voltage applied, the material through which the charges flow, and the state of the material.
1.3: Charge and Current - Engineering LibreTexts
Current (I) is the rate of flow of electric charge, and it is defined as the change in charge (Q) with respect to time (t), denoted as I=dQ/dt . This relationship is based on the fundamental principle that current is the flow of charge over time.
Electric Current Formula - Definition, Equations, Examples - Toppr
The magnitude of the flow of current at any section of the conductor is defined as the rate of flow of electrons. Mathematically, this can be represented as: I = \( \frac{Q}{t} \)
Physics Tutorial: Electric Current - The Physics Classroom
As a physical quantity, current is the rate at which charge flows past a point on a circuit. As depicted in the diagram below, the current in a circuit can be determined if the quantity of charge Q passing through a cross section of a wire in a time t can be measured.
