Answer Posted / Subhiksha Jaiswal
Negative loops are commonly used in Dc Logic Wiring due to their simplicity and reduced component count. By using a common collector (negative) configuration instead of common emitter (positive), one transistor can replace two or three needed for positive logic. If we use positive looping, more components would be required, which may increase the circuit's complexity and cost.
