Question

In a two terminals network the open circuit voltage measured at the given terminals is 110 V and short circuit currents at the same terminals 10 A. If a load of 50 Ω resistance is connected at the terminals, load current is ___________

(a) 1.8 A

(b) 1.25 A

(c) 6 A

(d) 6.25 A

I have been asked this question in homework.

This intriguing question comes from Advanced Problems on Application of Laplace Transform in section Application of the Laplace Transform in Circuit Analysis of Network Theory

Answer 1

Right answer is (a) 1.8 A

The best I can explain: RTH = \(\frac{110}{10}\) = 11 Ω

So, I = \(\frac{110}{50+11}\) = 1.8 A.
