Question

Three resistance of 30 ohm,10 ohm and 5 ohm are connected in parallel with 6 volt battery then calculate:total current drawn from the battery e and

Answer 1

Answer:

GIVEN THAT - R1 = 30 ohm

R2 = 10 Ohm

R3 = 5 ohm

V = 6 volt

TO FIND ----) Total current ( I net ) - ??

A.T.Q Three resistance are connected in parallel so by parallel combination ,

1 / Req = 1 / R1 + 1 /R2 + 1 / R3

1 / Req = 1 / 30 + 1 / 10 + 1 / 5

1 / Req = ( 1 + 3 + 6 ) / 30 = 10 / 30 = 1 / 3

Req = 3 ohm

So by ohms law , V = I X R , I = V / R

I net = 6 / 3 = 2 Ampere

Total current flowing is 2 ampere in the circuit
