Question

In the circuit shown, the total current supplied by the battery is (in Ampere)

Answer 1

Explanation:

if we arrange it , we will get circuit as shown in figure.

see figure, 6 ohm and 2 ohm are in parallel

so, resistance CB, R' = 6 × 2/(6 + 2) = 1.5 ohm

R' and 1.5 ohm are in series combination so,

R" = R' + 1.5 ohm = 1.5 ohm + 1.5 ohm

R" = 3 ohm

Finally, R" and 3ohm are in parallel combination so, Req = R" × 3ohm/(R" + 3ohm)

Req = 3 × 3/(3 + 3) = 1.5 ohm

now use Ohm's law, V = iReq

so, i = V/Req = 9/1.5 = 6A

hence option (C) is correct

Answer 2

Answer:

In Ohm's Law, the total current is equal to the total voltage divided by the total resistance. In a series circuit, the current is the same through all of the components in the circuit, whereas in a parallel circuit, the total current is only equal to the individual current in that branch of the circuit.
