Find the current flowing through the each resistor in parel 2 ohms and 3 ohm in series 4ohm a and 20 volt
That's better
R for 2 and 3 in parallel = 2*3/2+3 = 6/5 as we said before
If 4 ohm is in series with those then add R
total R = 6/5 + 4 = 26/5
current through 4 ohm = all of it = 20/R
= 20*5/26 = 100/26 = 3.85 amps
voltage across 4 ohm = 3.85*4 =15.38 V
voltage across two parallel = 3.85*6/5 = 4.62
check - those voltages better add to 20
they do
so
current through 2 ohm = 4.62/2 = 2.31 amp
current through 3 ohm = 4.62/3 = 1.54
amp
check - those currents better add to 3.85, they do
