Here's exactly what happens every time your heart beats 🫀 It starts with an electrical signal from the SA node — your heart's natural pacemaker. That signal tells your atria to contract, pushing blood down into the ventricles. Then the ventricles contract (ventricular systole): 🫀 Right ventricle → pumps deoxygenated blood to the lungs 🫀 Left ventricle → pumps oxygen-rich blood to the rest of your body After that, the heart enters diastole — a brief relaxation where the chambers refill and pre

Kirchhoff Circuit Law | It explains how current and voltage behave in an electrical circuit. There consist of two rules to the Kirchhoff Circuit Law. First of which is Kirchhoff's Current Law (KCL). The rule states that the total current entering a specific junction (or node) in a circuit must exactly equal the total current leaving it. The second rule is Kirchhoff's Voltage Law (KVL). It states that the algebraic sum of all voltage drops and voltage rises around any closed path (loop) in a circ
