Redo Ex2.2 with a 9V battery if the resistors are in SERIES instead of parallel. How much current passes through the resistors? How much voltage is across each resistor?
s(t) Same as positive terminal of vs(t) 13 R1 Σ1 ΚΩ R2500 Ω R3250 Ω 12 Same as negative terminal of vs(t) Figure 2-7: Circuit for Example 2-2. Example 2-2: Parallel Loads Three loads -a 1 ks light bulb, a 500 2 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.
