Question

Resistors connected in series generally always

select all that apply

1	dissipate more power than when hooked up in parallel
2	offer the biggest effective resistance compared to any other way of connecting them
3	dissipate the same amount of power each
4	have the same voltage across them
5	have the same current through them

Answer 1

To pick up answer have understanding of series resistance circuit as follows:

1)no, The power dissipated by each resistor is considerably higher in parallel than when connected in series to the same voltage source. Can be more clarified using some value of r1 r2 r3 in power formula.

Ps= i²Rs=(v/Rs)² *Rs=v2/Rs

Pp=v2/Rp

As equivalent resistance is more in series as sumed up rather than parllel so power is less is series

2)yes because in it equivalent resistance gets aaded up all together to produce bigger number whereas in parllel reciprocal then added then reciprocal again which makes value even shorteer then least resistance.

3)no, P=i²R current in series resistance goes same but power dissipated will now depend on resistance value more value of resistance more power dissipated

4)no due to series connection their is voltage drop across each resistance hence it cannot be same for all

5)yes, in series connection V(source) =I R_equivalent having current i goes same value in whole circuit.

Thus 2 & 5 is selected.
