The shock is strong enough to startle, but too brief to cause lasting harm. Engineers design these systems with capacitors and switches that release energy in controlled bursts, deterring animals or intruders without continuous current. It's electrical engineering turned into a safe but effective barrier. | Electricalgram | Facebook
