"Electrical ko amp" shabd se lagta hai ki aap "amp" (amphere) ko samajhna chahte hain. Amp, ya amphere, ek SI (International System of Units) unit hai, jo electric current ko measure karne mein istemal hoti hai.
Electric current, ya vidyut dhara, electrons ke flow ko darust karta hai. Amphere (A) is current ki unit hai. Agar aap kisi wire mein current flow dekh rahe hain, to amphere us current ki matra ko darust karti hai.
Mathematically, ek amphere ek coulomb charge ko ek second ke liye describe karta hai. Yani agar aapke wire mein 1 amphere ki current flow hai, toh 1 coulomb charge har second usse guzarti hai.
Isi tarah se, electric current ki measurement amphere mein hoti hai, aur yeh ek mahatva purna unit hai electrical engineering mein
Amphere (A) ko calculate karne ke liye, Ohm's Law ka use kiya ja sakta hai. Ohm's Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) between them. The formula for Ohm's Law is given by:
Where:
- is the current in amperes (A),
- is the voltage in volts (V),
- is the resistance in ohms ().
This formula helps you calculate the current (amperes) when you know the voltage and resistance in a circuit.
