Current Units Explained 🔌

Current (A, mA) measures the flow of electric charge - how much electricity is moving through a circuit.

Understanding current helps ensure circuits operate safely and efficiently.

Key Facts

  • 1 ampere (A) = 1,000 milliamperes (mA)
  • Amps are used for larger currents like motors and power supplies
  • Milliamps are used for small currents like LEDs and sensors

Formulas

  • mA = A × 1,000 - Convert amps to milliamps
  • A = mA ÷ 1,000 - Convert milliamps to amps

Example Currents

  • LEDs: 10–20 mA → 0.01–0.02 A
  • Smartphone charging: 1–2 A → 1,000–2,000 mA

FAQs

Why use milliamps?

Milliamps allow precise measurement of small currents in electronics.

How does current affect circuit safety?

Excess current can overheat components; fuses or resistors help protect circuits.
