SNC Me Ri R2 Rs Solutionhere R2 and R3 are parallel255255625

Solution

here R2 and R3 are parallel=(25*5)/(25+5)=6.25 ohms

6.25 ohms and 10 ohms are series=10+6.25=16.25 ohms.

16.25 ohms and 5 ohms are parallel=(16.25*5)/(16.25+5)=3.8235 ohms.

3.8235 ohms and 15 ohms are series=15+3.8235=18.8235 ohms

Req=18.8235 ohms

total current from the source=100/18.8235=5.3125 amps.

current through R5=5.3125 amps.

voltage drop across R5=5.3125*15=79.68 volts.

by using current division forrmula.

current through R4=(5.3125*5)/(5+6.25+10)=1.25 amps.

voltage drop across R4=1.25*10=12.5 volts.

current through R2=(1.25*5)/(5+25)=0.20833 amps.
