62 CIRCUIT CONCEPTS

termine the remaining voltages and currents. Also

calculate the power delivered to each element as

well as the algebraic sum of powers of all ele-

ments, and comment on your result while identi-

fying sources and sinks.

*1.3.2Calculate the voltagevin the circuit given in
Figure P1.3.2.
1.3.3Determinev,i, and the power delivered to el-
ements in the network given in Figure P1.3.3.
Check whether conservation of power is satisfied
by the circuit.
1.3.4For a part of the network shown in Figure P1.3.4,
given thati 1 =4A;i 3 (t)= 5 e−t, andi 4 (t)= 10
cos 2t, findv 1 ,v 2 ,v 3 ,v 4 ,i 2 , andi 5.
1.3.5For the circuit given in Figure P1.3.5, given that
VAC =10 V andVBD=20 V, determineV 1

andV 2. Show that the conservation of power is

satisfied by the circuit.

*1.3.6The current sources in Figure P1.3.6 are given to

beIA=30 A andIB=50 A. For the values of

R 1 = 20 , R 2 = 40 , andR 3 = 80 , find:

(a) The voltageV.

(b) The currentsI 1 ,I 2 , andI 3.

(c) The power supplied by the current sources

and check whether conservation of power is

satisfied.

1.3.7Show how the conservation of power is satisfied

by the circuit of Figure P1.3.7.

1.3.8Given thatV 0 =10 V, determineISin the circuit

drawn in Figure P1.3.8.
