You are to connect resistors R1 andR2, with R1 >R2, to a battery, first individually, then inseries, and then in parallel. Rank those arrangements according tothe amount of current through the battery, greatest first. (Useonly the symbols > or =, for exampleseries>R1=R2>parallel. )

The current is more in the parallel combination than in the series combination.

Explanation:

two resistances, R1 and R2 are connected to a battery of voltage V.

When they are in series,

R = R1 + R2

In series combination, the current is same in both the resistors, and it is given by Ohm's law.

V = I (R1 + R2)

..... (1)

When they are connected in parallel.

the voltage is same in each resistor.

The effective resistance is R.

So, the current is

..... (2)

So, the current is more is the parallel combination.

a, c, d, e are all applying about success strategies.

real, smaller and upside-down.   so the answer should be b.
