Question

Find the current through the 16.3 resistor and the 3.9V battery at the top of the circuit. Answer in units of A.
Due: Feb 27 2017, 11:00 pm (Central time) 4 The currents are flowing in the direction indicated by the arrows A negative current denotes flow opposite to the direction of the the arrow. Assume the batteries have zero inter- nal resistance. 3.9 V 16.3 23.32 14.8 V Find the current through the 16.392 resistor and the 3.9 V battery at the top of the circuit.

Explanation / Answer

v1 = 3.9 V gen.
v2 = 14.8 V gen

v1 conducting :
I11 = v1/16.3 = 3.9/16.3 = 0.239 A
I31 = I11 = 0.239 A
I21 = 0 (23.3 ohm res is shunted by g2)

v2 conducting :
Req = 16.3//23.3 = 16.3*23.3/(16.3+23.3) = 9.59 ohm
I32 = v2/Req = 14.8/9.59 = 1.543 A
I12 = I32*23.3/(23.3+16.3) = 1.543*23.3/ 39.6 = 0.9078 A
Currenth through 16.3 ohm :
I1 = I11+I12 = 0.239+ 0.9078 = 1.1468 A
