Question

Six volts is applied to a 2 ohm resistor in series with two 2 ohm resistors connected in parallel. The current through the first resistor is

Answer 1

Hi mate.


Thanks for asking this question.


Here is your answer,


First we can find the total resistance in the

circuit,



We know that.




For parallel combinations,

$\frac{1}{rp} = \frac{1}{r1 \: } + \: \frac{1}{r2}$


r1 = 2 ohm .

r2 = 2 ohm.



Therefore,

$\frac{1}{rp} = \frac{1}{2} + \frac{1}{2}$

$\frac{1}{rp} = \: \frac{1}{1}$

$rp \: = \: 1 \: ohm$


Total voltage in circuit,


V = 6 V.



We know that,

$i \: = \: \frac{v}{rp}$

$i \: = \frac{6}{1}$

$i \: = \: 6 \: ampere$




Thank you.
