Electric Field کا حساب کیسے لگائیں
Electric Field کیا ہے؟
Electric field strength measures the electric force per unit charge at a location. It's fundamental to electrostatics and electromagnet behavior.
فارمولا
The calculator applies E = kQ / r² for single charge, superposition for multiple
- E
- kQ / r² for single charge — kQ / r² for single charge
مرحلہ وار گائیڈ
- 1Enter the source charge and distance, or use field from multiple charges
- 2The calculator applies E = kQ / r² for single charge, superposition for multiple
- 3Results show electric field magnitude and direction

Q = 1 μC, r = 1 m
نتیجہ
E ≈ 8,990 V/m
Using k = 8.99 × 10⁹ N·m²/C²
عام غلطیاں جن سے بچنا ہے
- ✕Forgetting to square the distance
- ✕Confusing electric field with electric potential
اکثر پوچھے جانے والے سوالات
Is electric field direction standardized?
By convention, electric field lines point away from positive charges and toward negative charges.
How do you combine multiple electric fields?
Use vector superposition; add field vectors from all sources, accounting for direction.
