Explanation Light Year is the distance that light can travel in one year . The distance light travels in one year is known as light year . 1 light year is equal to 9.5 x 10¹²km . Last verified on 30-03-2026
Answer: flow of electric charge
Explanation A current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. The SI unit of electric current is the ampere.
بجلی کے فیلڈ کی توانائی کی کثافت کا ایس آئی یونٹ ______ ہے؟
Answer: J/m³
Explanation Energy density is defined as energy per unit volume , so the SI unit is joules per cubic meter (J/m³). It applies to electric fields where 𝑢 = 1/2𝜀𝐸² , with 𝑢 being energy density.
Answer: Volt
Explanation - Potential difference (V) is the work done per unit charge to move a charge between two points. - Formula: V = W/Q (where W = work in joules, Q = charge in coulombs) - 1 Volt = 1 Joule / 1 Coulomb - It tells us how much energy is used to move electric charges through a circuit.
