The figure shows a circuit containing an electromotive force, a capacitor with a capacitance of C farads (F), and a resistor with a resistance of R ohms (Ω). The voltage drop across the capacitor is Q/C, where Q is the charge (in coulombs, C), so in this case Kirchhoff's Law gives RI + Q/C =E(t) But I = dQ/dt, so we have R(dQ/dt) + 1/C (Q) = E(t) Suppose the resistance is 10 Ω, the capacitance is 0.05 F, and...

Consider the three basic quantities of a circuit: voltage (potential difference), current, and resistance. In general terms, describe each one in your own words and its basic characteristic/property, and can you do an analogy of these quantities with a fluid system, say a stream of water? Further, since many of you are in the medical field, can you relate a basic circuit and its components to a system of the body, maybe the circulatory system? If, what is the analogy...
