Question

Use Kirchhoff's Rules to find the currents I_1 I_2 and I_3 The total charge that on automobile battery con supply without being recharged .s given in terms of typical 28-V battery has a rating of 80 Ampere-hours Suppose you forget to turn off the in your period out womb If each of the two headlights draws 3 8 A. find out the time before your butter is 'dead'. A carbon rod with a radius of 0 29 mm is used to make o resistor The resistivity of this maternal is 3 5 What Length of the carbon rod should be used to make a resistor if the current is 1.45 A and the voltage h56V? A potential difference of 35 V is found to produce a current of 0.79 Amo wire of length 25m with a uniform radius of 05 cm A) what is the resistance of the wire' B) What .s the resistivity of the wire? A high voltage transmission Line with a resistance of 0 38 fl/km carries o current of 1100 A The

Explanation / Answer

(3) Firs of all net resitance of parallel combination of Resistance 1 and 2
1/R = 1/R1 + 1/R2
R = 2.22 Ohm
Now let us consider that the current Ia and Ib flow in the two loops
Loop 1 , using KVL
2.22 Ia + 6(Ia - Ib) + 5Ia = 6 -5
13.22Ia -6Ib = 1 -------(1)
Similarly for other loop
-6Ia + 18.22 Ib = 9.5 -------(2)
On solving 1 and 2
we get
Ia = 0.367 Ib = 0.6423
Now I1 = Ia , I3 = Ib
I2 = Ia - Ib = - 0.2753
