Question

How much current is being supplied by the current source? What is the power absorbed by the conductor?

Answer 1

`I=10A` and `P=50W`

Explanation:

The problem is giving us the conductance of the circuit in Siemens which is the reciprocal of the resistance in Ohms:

`R = 1/G = 1/(2S) = 0.5 \Omega`

The constant current being supplied generates `5V` across this resistance, so we can use Ohm's law to calculate the current:

`I = V/R = (5V)/(0.5\Omega) = 10A`

Finally the power absorbed by the conductor is given by Joule's law as:

`P=I*V = 10A*5V = 50W`
