How can i simulate the circuit below as it has no source. How can i insert the value of 9mA,8mA and 12mA current flowing through the wires.

Do you mean "simulate," or do you mean "solve?"

The arrows are the current sources.

You've got to learn Kirchhoff's current law and forget the simulation stuff until later. Kirchhoff's current law states that the sum of currents entering a node is zero.

Assume all currents flowing into a node are positive and currents leaving a node are negative (any assumption will work as long as you're consistent):

8mA - i1 - 12mA = 0: 8mA - 12mA = i1 = -4mA

12mA + i3 - 9mA = 0: -12mA + 9mA = i3 = -3mA

9mA - i2 - 8mA = 0: 9mA - 8mA = i2 = 1mA

Check: I2 + I1 - I3 = 0: 1mA + (-4mA) - (-3mA) = 1mA -4mA + 3mA = 0

Yes i know the current law. What i mean here is to make this circuit on computer and simulate it using orcad capture cis software or what will be the coding of pspice for this circuit.
