Hello, this might be an easy question but it's confusing for me. So please help.
Current flowing through an element is i(t)= 2e^(-t) and voltage across that conductor is v(t)= 2 (di/dt). Find out the charge is delivered to the element and power and energy consumed by the element in between 0 to 3 seconds.
I got charge as 1.9 C
I power as -8 e^(-2t) but when I asked my professor, he said I don't have to substitute t=3 in this.
But in energy he said i have to substitute t=3 in e = p*t.
What will be the final answers and why don't we substitute t=3 in power but we do in energy?
