v = iR ohms law

-1.5 + i1 + i2 = 0 kirchoffs law

What should i do to find i1 ?

You have written one equation with 2 unknowns.

You have to find another equation.

Use the Ohms law on parallel circuits.

Yes, but that is in the next chapter

Then you must have covered some other method(s). How about current dividers? KVL around a loop? Or, if you answered part (b) first and found the voltage ##v_o##, could you then find the currents?

Yes, KVL around a loop, but i dont know the current

-1.5 + i1 + i2 = 0

-1.5R + 100i1 + 150i2 = 0

-1.5 + i1 + i2 = 0

-1.5R + 100i1 + 150i2 = 0

Write the equation that shows: voltage across the 100Ω = voltage across the other pairYes, KVL around a loop, but i dont know the current

-1.5 + i1 + i2 = 0

[strike]-1.5R + 100i1 + 150i2 = 0 [/strike]
