Question

A battery having emf of 5v and internal resistance of 0.5ohm is connected with a redistance of 4.5ohm

Answer 1

Answer:

Use formula

I=E/R+r

You get the answer

Answer 2

Answer:

The current in the circuit is 1 A.

Explanation:

Given that,

Emf = 5 V

Internal resistance = 0.5 ohm

Resistance = 4.5 ohm

Suppose we find the current in the circuit

We need to calculate the current in the circuit

Using formula of current

$I=\dfrac{E}{R+r}$

Where, E = emf

R = resistance

r = internal resistance

Put the value into the formula

$I=\dfrac{5}{4.5+0.5}$

$I=1\ A$

Hence, The current in the circuit is 1 A.
