Find Value of I in Ohm's Law Circuit

Click For Summary
SUMMARY

The value of current I in the given Ohm's Law circuit is calculated using the formula I = V/R. The equivalent resistance R was determined to be 7.6 ohms, leading to a current I of 0.526 amperes when a voltage of 4 volts is applied. The calculation involved combining two 4-ohm resistors in parallel, resulting in an equivalent resistance of 4 ohms, and adding it to a 4-ohm resistor and a 1.6-ohm resistor. The final answer of 0.526 amperes was not listed among the provided options, indicating a potential oversight in the problem setup.

Homework Equations


## V = I R ##

The Attempt at a Solution


Leaving 4 ohm above resistor Equivalent R will be
##R_{eq} = \frac{4*4}{4+4} + 4 + 1.6 = 7.6##
##I = \frac{V}{R}##
## I = \frac{4}{7.6} = 0.526 ##
Ans is not given in the option please tell what I'm doing wrong

Why do you think you can ignore the top resistor?

Also, note that the middle contraption is two 4 ohm resistors in parallel with a wire of resistance zero ...
