Question

9. Consider the circuits given below :

(a) In which circuit are the lamps dimmest ?
(b) In which circuit or circuits are the lamps of equal brightness to the lamps in circuit (i) ?
(c) Which circuit gives out the maximum light?​

Answer 1

Answer:

a)ii

b)iii

c)iii

hope it helped you

Explanation:

i and ii are in series connection whereas iii is in parallel conection

Answer 2

Answer:

(a) Lamp will be dimmest in PARALLEL Circuit i. e., iii.

(b) ii.

(c)iii

Explanation:

(a) because the main current on entering the resistors divides in inverse proportion of resistance.

(b) because circuit (ii) is in series and the current flower in series connection remains same.

(c) because if I is the total current in circuit then

I1 &I2 are the currents in individual resistors.
