Norton equivalent

Question

Answer 1

(2)

Step 1:

Find the Norton's short circuit current.

1. Short the load resistor.

2. Calculate the Short Circuit Current. This is the Norton Current (I_N).

Redraw the circuit :

Resistor R₁ and R₂ are in series.

Step 2:

Now replace R₁ and R₂ with R.

Find the total circuit current : .

Voltage V = 50 +20

V = 70 V

Nortons equivalent resistance is .

Step 3:

Find the Current through the resistor R.

Use the CDR (current division rule ) to find the Current through the resistor R.

Norton short circuit current is .

Nortons current is .

Solution :

Nortons current is .
