Use the mesh-current method to find the branch currents ia, ib,
and ic in the circuit in figure also find currents ia, ib, and ic
if the polarity of the 64 V source is reversed. The values of v1
and v2 are 64 V and 30 V, respectively.

MULTISIM 4.36 a) Use the mesh-current method to find the branch PSPICE currents in, in, and i, in the circuit in Fig. P4.36. b) Repeat (a) if the polarity of the 140 V source is reversed. Figure P4.36 7512 150 12 Ic 80 V in 182000 140 V 1252 250 12 w w
if the frequency of the circuit is doubled. What
happens to IC IL and Is? trying to figure out the relationship
between frequency and current in an ac circuit

esign the current divider circuit shown in Fig. 5 such that it produces the branch currents of 16.67 mA, 10 mA, and 6.67 mA, as indicated. Since a true current source is not available, it is implemented here as a 15-volt source in series with a 100 Ω resistor. It is therefore necessary to choose Rı, R2, and Rs so that the total supplied current is Is- 33.33 mA, and the three branch currents are as shown. Table I -...
