Example 1: If a 1000Ω resistor is connected in parallel with a3000Ω resistor, what is the total or equivalent resistance? Alsocalculate total current and individual currents, as well as thetotal and individual dissipated powers.R R RR R1000 30001000 30003, 000, 0004000 750total1 21 2= ×+ = Ω × ΩΩ + Ω = ΩΩ = ΩTo find how much current flows through each resistor, applyOhm’s law:I VRI VR12 V1000 0.012 A 12 mA12 V3000 0.004 A 4 mA111222= = Ω = == = Ω = =These individual currents add up to the total input current:Iin = I1 + I2 = 12 mA + 4 mA = 16 mAThis statement is referred to as Kirchhoff’s current law. Withthis law, and Ohm’s law, you come up with the current divider
Great intro problem to Kirchhoff's current law
Current divider notes as well!
