Final answer:
The power flowing into the electrical sink can be determined by multiplying the voltage by the current. To calculate the energy absorbed or generated, we integrate the power over time.
Step-by-step explanation:
The power flowing into an electrical sink can be determined by multiplying the voltage (V) by the current (I). In this case, the voltage is given as 340sinwt V and the current is 5.6sinwt A. To calculate the power, we can use the formula P = IV.
P = (340sinwt)(5.6sinwt) = 1904sin^2(wt) W.
To determine the energy absorbed or generated during a 10s period starting at t=0, we integrate the power over time:
Energy = ∫P dt = ∫(1904sin^2(wt)) dt = 1904∫(0.5 - 0.5cos(2wt)) dt
After evaluating the integral over the given time period, we can find the total energy absorbed or generated.
