Question

Consider the circuit shown in the figure(Figure 1) . Suppose the four resistors in this circuit have the values R1 = 10? , R2 = 8.0? , R3 = 7.7? , and R4 = 14? , and that the emf of the battery is E = 15V .


Find the current through each resistor using the rules for series and parallel resistors.


Find the current through each resistor using Kirchhoff's rules.

Explanation / Answer

-i2*R2-i2*R4+i3*R3=0...(1)

V-i3*R3-i1*R1=0....(2)

i2=i1-i3....(3)....by solving these 3 eqns...we get


current through R1=0.955 A..
through R2 and R4 is0.248 A
through R3 is 0.707 A
