A current of 11 amperes branches into currents x, y, and z through resistors with resistences 6, 5, and 3 ohms as shown. 1=x, R=6 I=y, R=5 I=11 amps 1=2, R=3 It is known that the current splits in such a way that the sum of the currents through the three resistors equals the initial current. The energy generated in each resistor is given by E = I'R, where I is the current in that resistor and R is the...
