Using the data below of two different series circuits, and in just a few sentences, how does the value of the current change throughout the circuit? In other words, why hasn't the current changed and remained constant in the two series circuits?

Three Equal Resistors Resistance, Q Current, A R1 = 5.00 Q lo = 0.60 A R2 = 5.00 0 11 = 0.60 A R3 = 5.00 0 12 = 0.60 A 13 = 0.60 A Three Unequal Resistors Resistance, Q Current, A R1 = 5.00 Q lo = 0.26 A R2 = 10.0 0 41 = 0.26 A R3 = 20.0 0 12 = 0.26 A 13 = 0.26 A
