Electric current

Electric current, electric charge ke bahanaa hae. Ii bahanaa electrons se koi conductor me hoe hae. Current ke equation hae:^[1]

${\displaystyle I={\frac {\Delta Q}{\Delta t}}}$

where

${\displaystyle I}$ jon current bahe hae

${\displaystyle \Delta Q}$ electric charge me antar

${\displaystyle \Delta t}$ ketnaa samay bitaa hae

Electric current ke SI unit ampere (A) hae. Ii ek coulomb, har ek second me, ke charge ke baraabar hae. Electric current ke wires, batteries, aur lightning me paawa jaae hae.

Jab current ek taar waala circuit me bahe hae, tab iske raftaar jaada hoe lage hae. Resistor se circuit me current ke raftaar ke kamtii karaa jaae hae. Resistance, current aur voltage ke biich ke sambandh ke Ohm's Law me dekhaawa jaae hae. Iske formula hae: V=IR, jisme V hae potential difference, volts me, I hae current, amperes me, aur R hae resistance, ohms me.
