If RC is small the capacitor charges quickly; if RC is large the capacitor charges more slowly. time current 0 Io 1*Ï Io/e = 0.368 Io 2*Ï Io/e2 = 0.135 Io 3*Ï Io/e3 = 0.050 Io An RC Circuit: Discharging.nitially the potential difference across the resistor is the battery emf, but that steadily drops (as does the current) as the potential difference across the capacitor increases. Applying Kirchoff's loop rule: Îµ - IR-Q/C = 0. As Q increases I decreases, but Q changes because there is a current I.
The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. This system is comprised of the heart and the circulatory system. Structures of the cardiovascular system include the heart, blood vessels, and blood.The lymphatic system is also closely associated with the cardiovascular system.tructures of the Cardiovascular System. 1  Heart. 2  The heart is the organ that supplies blood and oxygen to all parts of the body. 3  This amazing muscle produces electrical impulses through a process called cardiac conduction. 4  These impulses cause the heart to contract and then relax, producing what is known as a heart beat.
The four major functions of the cardiovascular system are: 1. To transport nutrients, gases and waste products around the body. 2. To protect the body from infection and blood loss. 3. To help the body maintain a constant body temperature (âthermoregulationâ). 4.his circuit pumps deoxygenated (blue) blood from the heart to the lungs where it becomes oxygenated (red) and returns to the heart. The systemic circuit is made up of the heart and all the remaining arteries, arterioles, capillaries, venules, and veins in the body.
