Question

plz koi solve kar dooo yaalll


A battery of emf 10 V and internal resistance 3 ohm is connected to a resistor. If the current in the circuit is 0.5 A, what is the resistance
of the resistor? What is the terminal voltage of the battery when the circuit is closed???​

Answer 1

Answer:

I just solved the same question hope I helped u

Answer 2

Answer:

emf of battery=10v

r, internal rssitance of battery=3 ohmscurrent in th circuit,I=0.5A

Resistanc of the rsistor=R

Ohm's law

I=E/(R+r)

So, R=17 ohms

Terminal voltage of the reesistor=V

Ohm's law states that

V=IxR

So, V= 8.5V
