PLEASE HELP!! ALL THREE PARTS!! THANK YOU111

PART A

Determine the magnitude of the current through resistor R3, shown in the figure below. The batteries have emfs of E1 = 6.00 V and E2 = 9.00 V and the resistors have values of R1 = 12.6 ? , R2 = 21.0 ?, and R3 = 31.9 ?.

PART B

Determine the magnitude of the current through resistor R1.

PART C

Determine the magnitude of the current through resistor R2.

Determine the magnitude of the current through resistor R3, shown in the figure below. The batteries have emfs of E1 = 6.00 V and E2 = 9.00 V and the resistors have values of R1 = 12.6 ? , R2 = 21.0 ?, and R3 = 31.9 ?. Determine the magnitude of the current through resistor R1. Determine the magnitude of the current through resistor R2.

Explanation / Answer

E1 = 6.00 V and E2 = 9.00 V and the resistors have values of R1 = 12.6 ? , R2 = 21.0 ?, and R3 = 31.9 ?.

Let currents through R1,R2,R3 be i1,i2,i3

KVL equations =>

6 - 12.6*i1 = 21*i2

21*i2 = 9 - 31.9*i3

i2 = i1+i3

by solving these equations,

i1 = 0.096 A

i3 = 0.132 A

i2 = 0.096+0.132 = 0.228 A

PART A

Determine the magnitude of the current through resistor R3,

i3 = 0.132 A

PART B

Determine the magnitude of the current through resistor R1.

i1 = 0.096 A

PART C

Determine the magnitude of the current through resistor R2.

i2 = 0.228 A
