In the resistor\'s combination shown in the figure at right R11.0 , R2 10 , R3 5.0 2y R4 2.0 2. If the current in R3, 13 2.0 A, then the voltage between points a and b is R2 a) 2 V d) 18 V b) 10 V. e) Another answer. Which one?:_ c) 11 V R, R, R,
Solution
Solution:
Given the current across R3 is = 2.0 A
Voltage accross R3 = V3 = I3 * R3 = 2 * 5 = 10 V
As in parallel voltage remains same ,
Current across R2 = 10 /10 = 1 A
current across R4 = 10 / 2 = 5 A
total current = 5 + 1 + 2 = 8 A
So 8 A is the current passing through R1
voltage accros R1 = 8 * 1 = 8 V
Voltage between a and b = 10 + 8 = 18 V
.
