Question

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. $220volt$
• B. $440volt$
• C. $200volt$
• D. $400volt$

Answer 1

The correct option is D $400volt$

Total resistance of the circuit$=4000+400=4400W$
Current flowing $i=\frac{V}{R}=\frac{440}{4400}=0.1A$.
Voltage across load $V_L=Ri=4000\times 0.1=400V$.
