Question 1. Indicate whether the following statements are TRUE or FALSE. Choose the answer and write only 'true' or 'false' next to the question number (1.1.1-1.1.10) on your assignment page. 1.1.1 A non-sinusoidal waveform is any waveform that is not a sin wave and is also not sine-like. 1.1.2 Form factor is defined as the rms of the ratio value of the wave to its average value. 1.1.3 Resistance opposes current flow and in the process produces heat. 1.1.4 In any balance three-phased load the impedance of each phase (Ip) is equal. 1.1.5 Power factor is defined as the ratio of true power to apparent power. 1.1.6 Three-phase loads can be connected in either star/star or delta/delta. 1.1.7 The average value represents the average value of all mid-ordinates taken over a full cycle of a sine wave. 1.1.8 In any unbalanced three-phased load the impedance of each phase (Zp) is not equal. 1.1.9 Three-phase loads can be classified as either balanced or unbalanced. 1.1.10 In a purely resistive circuit, the voltage is always in phase with the current.

1.1.1 false 1.1.2 false 1.1.3 true 1.1.4 true 1.1.5 true 1.1.6 true 1.1.7 false 1.1.8 true 1.1.9 true 1.1.10 true Did you know that the concept of alternating current (AC) was popularized by Nikola Tesla in the late 19th century? Tesla's work laid the foundation for modern electrical systems—his innovative AC motors and transformers made it possible for electrical power to be transmitted over long distances, revolutionizing how we power our homes and industries! When working with waveforms and electrical loads, one common mistake is confusing the terms "average value" and "rms value." They serve different purposes! The average value is particularly useful for calculating DC equivalent values, while the rms value is essential for understanding the actual power delivered by an AC signal. Don't mix them up, or you may end up miscalculating your power needs!
