    A generator has an e.m.f. of 440 Volt and internal resistance of 400 Ohm. Its terminals are connected to a load of 4000 Ohm the voltage across the load is

    A) 220 volt

    B)        440 volt

    C) 200 volt

    D)        400 volt

    Correct Answer: D

    Solution :

    [d] Total resistance of the circuit \[=4000+400=4400\Omega \] Current flowing \[i=\frac{V}{R}=\frac{440}{4400}=0.1\,amp.\] Voltage across load= R i             \[=4000\times 0.1=400\,volt.\]
