Electro Magnetic Induction And Alternating Currents Question 505
Question: A generator has an e.m.f. of 440 Volt and internal resistance of 4000 hm. Its terminals are connected to a load of 4000 ohm. The voltage across the load is
Options:
A) 220 volt
B) 440 volt
C) 200 volt
D) 400 volt
Show Answer
Answer:
Correct Answer: D
Solution:
-
Total resistance of the circuit = 4000 + 400 = 4400 W Current flowing
$ i=\frac{V}{R}=\frac{440}{4400}=0.1amp $
Voltage across load = $ Ri=4000\times 0.1=400 $ volt.
