Example 2-2: Parallel Loads
Three loads-a 1 ks2 light bulb, a 500 s2 computer, and a 250 2
TV, each represented by a resistor, are connected in parallel to a
household ac voltage source as shown in Fig. 2-7. The source is
cosinusoidal in time at a frequency of 60 Hz and its amplitude
is 170 V. Hence, it can be described as
us(t) = 170 cos(2л x 60t) 170 cos (377t) V.
Determine the currents supplied by the source to the three loads.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb2f5b0ad-df1d-48c6-a9a3-5338b8167143%2Fc9c28929-0d0d-4575-a042-528bc2b779ef%2Fqnfxl1e_processed.jpeg&w=3840&q=75)
