Question

find equivalent resistance and current through 7 ohm resistor in following.​

Answer 1

Explanation :

From the given figure,

(1) and resistors are in parallel. There equivalent is given by :

and resistors are in series.

So,

(2) According to Ohm's law :

(3) Voltage across resistor is

Hence, this is the required solution.

Answer 2

Answer:

R=16Omhs

I=0,8A

Explanation:

Rtotal=7+8

=15omhs

I=0.8

then

R=V÷I

15I=12

divide by 15 both side then I=0,8
