Question

The circuit above contains 5 resistors (R1, R2, RA, RB, RC) with equal resistance R. Write an equation for the current i2in terms of the current i1. ( when entering your answer, use i1 for i1, e.g.,the answer 0.5*i1 has the correct syntax)

i2 =

The circuit above contains 5 resistors (R1, R2, RA, RB, RC) with equal resistance R. Write an equation for the current i2in terms of the current i1. ( when entering your answer, use i1 for i1, e.g.,the answer 0.5*i1 has the correct syntax) RA = RB = RC = R1 = R2 = R

Explanation / Answer

current through RB and R2 are equal as they are in series

By current divider rule

Ib =I2 =I1*(Rc/Rc+(Rb+R2))

I2 =I1*(R/3R)

I2 =0.33I1
