ow can three resistors of resistance 20, 30 and 60 be connected to
give a total resistance of
(a) 40 (b) 9Q?
II) What are the advantages of connecting electrical devices in parallel
with the battery instead of connecting them in series?

Explanation:
(a) we connect 30 and 60 in parallel with 20 in series to get 40 ohm.
(b)is this 9 or 90
the overall resistance became low and when we connect the electrical devices in parallel combination we can use them separately.

Answer:
1)Refer to the attachment ♥️♡♥️
2)When the electric appliances are connected in parallel then each device get same potential difference also the total effective resistance is reduced.
