पृथ्वी 23.5° झुकी क्यों है? | पृथ्वी का झुकाव और प्रीसेशन का रहस्य 🌍
क्या आप जानते हैं कि पृथ्वी 23.5° झुकी हुई है और इसकी धुरी लगभग 26,000 वर्षों में एक पूरा चक्र बनाती है? जानिए पृथ्वी का झुकाव (Axial Tilt), प्रीसेशन (Precession), ऋतुएँ कैसे बनती हैं ध्रुव तारा क्यों बदलता है
Georg Ohm's foundational principle connects voltage across a conductor to the current it carries through its resistance.
Starting from the electric field integral defining potential difference and current density over a cross-section, the relations simplify for constant fields and uniform materials to V = RI.
Straight-line graphs illustrate constant resistance in ohmic components such as resistors, while curved plots reveal changing resistance in non-ohmic elements like diodes.
Circuit designers apply the law to compute required resistances and currents when building safe and efficient electronic devices and power systems.
