1. The problem statement, all variables and given/known data In my lab today, I created a circuit with resistor (R1) in series with a set of resistors in parallel (R2//R3). Using an ammeter, I measured: I1 = 2.30mA I2 = 1.25mA I3 = 0.38mA 2. Relevant equations Junction Rule: ΣI = 0 3. The attempt at a solution So applying the Junction Rule, I1 = I2 + I3 However, with what I've measured, 12+13 does not add up to I1. What could cause this "loss" of charge? To me, this doesn't make sense, as this violates the idea of conservation of charge. How can charge just disappear like such, after the parallel connection converges?
