Answer to Question #317992 in Physics for Davzz

Question

Three resistors R1=1.00Ω , R2=2.00Ω , and R3=2.00Ω , are connected in series The series connection is attached to a V=3.00V voltage source.

a. What is the equivalent resistance?

b.find the current supplied by the source to the series circuit?

Answer 1

a. What is the equivalent resistance?

$$R_{eq}=R_1+R_2+R_3\\ =1.00+2.00+2.00=5.00\:\Omega$$

b.find the current supplied by the source to the series circuit?

$$I=\frac{V}{R_{eq}}=\frac{3.00}{5.00}=0.600\:\rm A$$
