Question

A circuit consists o two batteries with negligible internal resistance six ohm1c resistors, and connecting wires that have negligible resistance. The resistance R1 IS 10 R2 ls 20 Q, R3 ls 30 Ra is 12 15 , and R6 is 20 . Unknown currents 11-12, 13, 4-5, and 16 have their direction5 marked on the circuit diagram in the figure below Rs is I2 R4 Loop 1 (a) Write down a set of equations that could be solved for the six unknown currents, Make sure you can explaln how you got these equations, (Select all that apply.) 11-12 + 14 20 1011 - 154 -12ls- 2010 -3013+121s - 5-0 S + 1514-2012-0 12-15 + 13 301312iG - 5-0 20 101514 121 201 11-13 + 16 11 = 6-13

Explanation / Answer

Given,

a)The correct equations are:

I1 = I2 + I4

I2 = I5 + I3

I1 = I3 + I6

b)Vgc = Vc - Vg

Vgc = 20 - 10 x 0.4394 - 20 x 0.4394 = 6.82 V

Hence, Vgc = 6.82 V

d)You got it right

P = 0.3247 x 5 = 1.624 W

Hence, P = 1.624 W

d)V4 = 0.1082 x 15 = 1.623

E = V/d = 1.623/0.7 x 10^-3 = 2.32 x 10^3 V/m

Hence, E = 2.32 x 10^3 V/m
