Electric Current and Ohm Law

Jul 4, 2026 · 1 min read · 0 views

Electric Current

Electric current is the flow of electric charge through a conductor. It is measured in amperes (A).

Voltage and Resistance

Voltage (V): the push that drives the current, measured in volts.
Resistance (R): opposes the flow of current, measured in ohms.

Ohm Law

Ohm law states that current equals voltage divided by resistance: I = V / R.

Key Points

Increasing voltage increases current, while increasing resistance decreases it.
