On this occasion, I will discuss how to calculate the voltage current and electric power included with the calculating formulas.

However, because the title is less specific for calculating and the formulas, apart from that, there is also no formula for calculating power. Therefore, let me write it here.

### Definition of current, voltage, and electric power

Current in electrical terms is called Ampere (I), which means the amount of electric charge that flows through a point in an electric circuit per unit of time. The unit of electric current is called the Coulomb or Ampere.

Because the electric current is defined as the amount of electric charge that flows, of course, it is very much influenced by the amount of voltage and resistance of a conductor.

To make it easier, you can imagine the water that will flow if the position of the main water point is higher and leads to a lower point. Imagine if the position of the main point and the next point are parallel. Then current will only flow if there is voltage.

Voltage in electrical terms is called Volt or Voltage (V) which means the difference in electric potential between two points in an electric circuit and is expressed in units of V (Volt). This quantity measures the potential energy of an electric field which results in the flow of electricity in an electric conductor.

Depending on the difference in electric potential, an electric voltage can be said to be extra low, medium, high to extra high.

To make it easier to understand, you can imagine a children’s toy water gun. Water will come out if there is pressure on the trigger of the gun. Conversely, if there is no pressure on the trigger gun, water will not come out. The pressure on the trigger of the gun can be assumed to be the tension.

Power in the electrical language is called Watt (P), which means the rate of energy delivered or work done per unit time. Power is denoted by P (Power). In other words, electric power is the level of energy consumption in an electric circuit or circuit.

For example, an incandescent lamp absorbs the electric power it receives and converts it into the light.

### How to calculate the Voltage Current and power?

**Calculate the electric current**

I = Electric current

V = voltage

R = Resistance (ohms)

P = power / power

Q = Coulomb

T = time in seconds

Problems example

The time needed to flow a conductor is 5 minutes with an electric charge of 1000 coulombs. How strong is the current in a conductor wire?

Known

Q = 1000 Coulomb

t = 5 minutes = 300 seconds

asked I?

Answer

I = Q / t

I = 1000/300

I = 3.33

So the current in a conductor is 3.33 Ampere
