If the total circuit dissipation is 1.44 Watts on a three branch parallel resistor and branch 1 is half the current value of branch 2 and one third the current value of branch 3; v applied to the circuit is 120V.
What are the v, i, r, and p values for the circuit and for each branch

Michelle,

Draw your circuit and get into the habit of constructing a table like the one I attached illustrating for your problem.

Fill in the knowns and think about the problem.

HOPE THE ATTACHMENT HELPS - CHECK LIBRARY FOR ELECT ENGRG BOOK WITH KIRCHOFF'S LAWS
SHOULD EXPLAIN MY LOGIC IN ATTACHMENT[attachmentid=995]
