Electric current is a fundamental concept in electrical engineering, physics, and many other fields. It is the rate at which electric charge flows through a circuit, and it can be calculated by using the relationship between electric charge, electric current, and time. To determine the electric current, one must first measure the amount of electric charge that flows through the circuit during a given period of time. This can be done using a device called an ammeter.

The ammeter measures the current flowing through the circuit in units of amperes (A), which is the same as Coulombs per second (C/s). The amount of electric charge that flows through the circuit can be determined by multiplying the current by the time. This relationship is known as Coulomb's law and is expressed mathematically as Q = I x t, where Q is the amount of electric charge, I is the electric current, and t is the time.

Knowing the electric current is essential for designing and analyzing electrical circuits. It allows engineers to determine the amount of power being consumed by a circuit, as well as to optimize the circuit's performance for specific applications. Additionally, measuring the electric current is crucial for safety reasons, as it can help prevent electrical fires and other hazards.

In summary, determining electric current is a fundamental aspect of electrical engineering and physics. By using Coulomb's law, which relates electric charge, electric current, and time, one can easily calculate the electric current flowing through a circuit. This information is crucial for designing and analyzing circuits, optimizing performance, and ensuring safety.

An alternative formula for determining the electric current can be derived from:
\(Q\) \(=\) \(I\) \(\cdot\) \(t\)
\(I\): The electric current
\(Q\): The electric charge
\(t\): The duration
The SI unit of electric is: \(ampere\text{ }(A)\)

Find I
