Human circulatory system and circuit breakers:

Circulatory system (a) Use Kirchhoff’s rules to determine the current in each branch of the circuit shown in Figure P16.58 for the case in which e = 90 V, R1 = 10 ?, R2 = 30 ?, and R3 = 60 ?. (b) Repeat the current calculations if R1 increases to 30 ?, while R2 and R3 remain unchanged. (c) Discuss briefly how this electrical circuit is analogous to the circulatory system of a person and the effect of a decrease in the size of a main artery on the flow of blood to other parts of the body.
