For everyone confused about how the power is 0 : The energy is 2J. When we calculate power, we calculate the average power of the signal as a whole. Hence, Power is basically the energy divided by the total time. But the total time is infinite. Hence P = 2J/infinity = 0 Hope this helps :)

Very nicely presented, cleared my basic knowledge. Thanks mam, really appreciate your effort.

What you are explaining Can understand yourself

[@maheshvishnoi3579]

Ma'am power of this signal is non zero and energy also, but according to your previous lectures the power of energy signal is must be zero. But that rule is not applicable here. So please me this query

[@samuelude6858]

Thanks a lot you are really doing a great job here.

In this problem. Energy limits is -T to T, but you took the values 0 to 2 . I think it's not right answer. As you said power is zero,when energy has a valued. While calculating power with those limits ,the ans.= 1W. Is this correct???

[@vakhariyajay2224]

Thank yoy very much .

[@pratyushkesharwani2179]

In formula of energy , there is integration of inside function but when you find out from 0 to 2 then you haven't squared it . It that right or wrong.

Mam u explained for discrete signals that for P+E=P.but u r applying it for continuous ramp signal

[@anuragpatel8276]

thanks to u mam and to turorial academy

[@physicsncertads2606]

Nice explanation

[@pardeepgarha6192]

Thanku mam U r awesome 🙏👌

[@shams0255]

How power becomes zero...please calculate..

[@arundeva2700]

From picture u told power signal ,after that u l calculate energy signal

[@ashokbanjara6323]

Osm nyc explain mam

[@Adhi0209]

Mam Can a signal be both energy and power signal? How it is possible

[@nishantbindhani9434]

isn't the formula for calculating rhe energy is |x(t)|^2 so maybe instead of integreting t it should be t^2 and ans should be 8/3

[@amittak8135]

How power is coming zero tell by integrating

Ma'am may I go to the toilet
