Question

How is DC current calculated?

Answer 1

DC current:

1. Electrical current that constantly travels in a single direction is known as a direct current (DC).
2. Direct current is the type of current that circulates in a flashlight or other battery-operated device.

Calculation of DC current:

1. Once the current is formed, DC voltage and current remain constant over time:

2. A time-versus-voltage and current graph for $60-Hz$ AC power. For a straightforward resistance circuit, the voltage and current are sinusoidal and synchronized. AC sources come in a variety of frequencies and peak voltages.

3. Now, using the Ohm's law, the strength of a direct current is inversely related to the resistance of the circuit and directly proportional to the potential difference,

$V=I\times R$, where $V=$voltage, $I=$current, and $R=$resistance.

4. It is possible to determine power using the formula if the values of voltage and current are known.

5. The rate at which electric charges move across a conductor is known as current. Voltage (V) and current (I) together produce electrical power. It is given by,

$P=V\times I$ .
