A resistor of resistance 100 Ω is connected to an AC source ϵ = (12 V) sin (250 π s–1) t. Find the energy dissipated as heat during t = 0 to t = 1.0 ms.

Given: Resistance (R) =100 Ω

Source emf ϵ = (12 V) sin (250 π s–1) t


T=1.0 ms =10-3 s.t


Then, energy dissipated (E) will be




Since,




On integrating,
