GCSE Science/Electricity multiple choice practice question 3 answer 3

From Wikibooks, open books for an open world

I'm sorry but this is the wrong answer. Remember that each branch has the entire voltage across it.

Applying Ohm's law to the top branch:

I=V/R

=6/4 A

=1.5A

The lower branch has a combined resistance of 4Ω because the two resistirs are in series.

Applying Ohm's law to the bottom branch: I=V/R

=6/(2+2) A

=1.5A
