In the figure, R1 = 10.0 ohms, R2 = 50.0 ohms, and R3 = 25.0 ohms. If a current of I2 = 0.128 A flows through resistor R2:
1) Find the voltage drop across the resistor R2
2) Find the voltage drop and current for resistor R1
3) Find the voltage drop and current for resistor R3

1)
voltage drop across R2= R2*I2
=50* 0.128
=6.4 v
2)
voltage drop across R1= voltage drop across R2= 6.4 V
Because R1 and R2 are in parallel

3)
I1= V1/R1
=6.4/10
=0.64 A
I3= I1+I2
= 0.64+ 0.128
=0.768 A
voltage drop across R3= R3*I3
=25 * 0.768
=19.2 v
