Answer 1

Explanation:

ANSWER:-

Basics of Parallel Combination:-

• Parallel combination is the reciprocal of summession of Resistances
• According to Formula, if I take Parallel Resistance AS x,

$\frac{1}{x} = \frac{1}{y1} + \frac{1}{y2} + \frac{1}{y3}$

• Where y1, y2 and y3 are other Resistances
• So, we can see that
• The value of actual Resistance decreases when combined in Parallel combination.

We derive that Parallel resistances actually decrease the resistance as offered earlier due to reciprocal.

Basics of Series combination:-

• Series combination is simple addition of all Resistances
• According to formula, if x is equivalent resistance

$x = y1 + y2 + y3$

• Where all y1, y2 and y3 are other Resistances
• So, series resistances increase the resistance AS offered earlier.

According to Question:-

• We need to find the parallel resistance
• As A has lower path, A is having parallel combination due to less resistance offered .

Things to Note:-

• Always see whether there is V-I or I-V graph
• I-V graph tales the reciprocal of Resistances.
• This graph is a V-I graph, so resistances are taken standard.

Hence, A is the option.

Answer 2

A as in a parallel connection the individual resistance is more than total resistance
And in a series it is less than total
So for the same resistors series will have more resistance
And in a VI graph steeper sloops has more resistance than flatter one .
