Question

In the figure given below, the Norton Resistance, as seen at the terminals P-Q, is given by __________

(a) 5 Ω

(b) 7.5 Ω

(c) 5 Ω

(d) 7.5 Ω

Answer 1

Correct choice is (a) 5 Ω

Easy explanation: For finding VN,

VN = (frac{4 × 10}{10+10}) = 2V

For finding RN,

RN = 10 || 10

= (frac{10×10}{10+10}) = 5 Ω.
