The amount of charge enters (and leaves) is 12 Coulomb.
<h3 /><h3>How can we find the value of the amount of charge enters (and leaves)?</h3>Here we are using the formula,
and
We are given,
P = Power of the light bulb = 25 Watt.
V = The amount of voltage where the light bulb operated = 120 Volt.
t= The time when charge enters (and leaves) the light bulb = 1.0 min = = 60 S
We have to find,
I= The amount of current flows in the light bulb.
Q= The amount of charge enters (and leaves) the light bulb.
Now we substitute the values of known parameters in the first equation, we find that,
Or,
The amount of current flows in the light bulb is 0.20 Ampere.
Now, we put the value of I in the second equation,
Or,
So, from the above calculations we can see that the amount of charge enters (and leaves) the light bulb is 12 Coulomb.
