In a two-terminal network, open-circuit voltage mesured at the given terminals by an electronic vol t met er is 100 V. A short -circuit current measured at the same terminals by an ammeter of negligible resistance is 5 A. If a load resistor of 80 Ω is connected at the same terminals, then current in the load resistor will be ________ A

Correct Option: A
ZTH = | = | = 20 | ||
ISC | 5 |
Total resistance, Z = ZTH + 80 = 100 Ω
∴ Current, I = | = 1 A | |
Z |
