The three incoming currents at a node in an electrical circuit measure 0.7 amps, 0.68 amps, and 0.47 amps. Two of the three outgoing currents measure 0.8 amps..

Question

...and 0.55 amps. Find the measure of the third outgoing current

Answer 1

At a node, the sum of the incoming currents must equal the sum of the outgoing currents.

 

0.7 + 0.68 + 0.47 = 0.8 + 0.55 + I₃

 

Can you finish from here and find I₃ in amps?
