STEP 0: Pre-Calculation Summary

Formula Used

Current = Voltage/Resistance
I = V/R
This formula uses 3 Variables

Variables Used

Current - (Measured in Ampere) - Current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.
Voltage - (Measured in Volt) - Voltage, electric potential difference is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points.
Resistance - (Measured in Ohm) - Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms.

STEP 1: Convert Input(s) to Base Unit

Voltage: 22.5 Volt --> 22.5 Volt No Conversion Required
Resistance: 30 Ohm --> 30 Ohm No Conversion Required

What causes the electrons to move?

Voltage is the “outside force” that causes electrons to move. Voltage is potential energy. Potential energy has the ability to perform work. An example of potential energy is an axe being held above a piece of wood. If the axe is allowed to drop onto a piece of wood, then the wood would split. Notice the word “if” appears. Potential energy does work ONLY if it is allowed to do so.

How to Calculate Current in DC Circuits?

Current in DC Circuits calculator uses Current = Voltage/Resistance to calculate the Current, The Current in DC Circuits formula is defined as a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.
