Question 7 (a) Select all that apply The equation for instantaneous power is as follows: p(t) = ½ VmImcos(0,₁– 0;) + ½ Vmlmcos(2wt + 0, + 0;) Identify the features of the expression for instantaneous power. (b) The instantaneous power has two parts. The first part is independent of time. The second part is a sinusoidal function whose frequency is 3w. The value of the first part depends on the phase difference between the voltage and the current. Consider a load R₁ attached to a circuit that can be represented by its Thevenin's equivalent RTH. Identify the condition when the power delivered by the power- supplying resistive network to the load is maximum. RL = RTH RL = (RTH)² RL = RTH/2 RL=√ RTH
