Question

Draw a schematic diagram of a circuit consisting of a battery of 3 cell of 2V each a combination of three resistors of 10,20,30 connected in parallel a plug key and an ammeter all connected in series

Answer 1

Answer:

voltage of each cell = 2 V

number of cells = 3

total voltage of the battery = 3 x 2 = 6 V

R1 = 10 ohm

R2 = 20 ohm

R3 = 30 ohm

All the resistances are in parallel.

So, the equivalent resistance is given by
