How many 75-W lightbulbs, connected to 120 V as in the figure, can be used without blowing a 12A fuse?(Figure 1) How many 75-W lightbulbs, connected to 120 V as in the figure, can be used without blowing a 12A fuse?(Figure 1)
several 60 w light bulbs are connected in parallel to a 120 v source. the circuit has a circuit breaker cb that is placed right after the battery that interrupts the current through itself whenever that current exceeds 9 A. Calculate the largest number of bulbs that can glow together.
How many 60 W lightbulbs can be hooked in parallel to 120 V without blowing a 10 A fuse? (see Fig. 25- 20 for a picture of the circuit.)
Determine the maximum number of 50 w/100 v light bulbs that can be connected together in parallel so as not to burn out a 15 A fuse when the bulbs are powered by a 75 v source (assume that the resistance of the fuse is negligible). A.40 B.30 C.20 D.10
QUESTIONS A bird stands on a dc electric transmission line carrying 5000 A. The line has 49 10-3 a resistance per meter, and the bird's feet are 3 cm apart. What is the potential difference between the bird's feet? QUESTION 6 How many 35-W light bulbs, connected to 120 V battery in parallel, can be used without blowing a 11.A fuse?
(a) What is the resistance of ten 100-W light bulbs connected in parallel? (b) in series? The resistance of a 100-W, 120-V light bulb is 144 Ohms.
Two light bulbs are connected in parallel, and then connected to a battery, as shown in Fig. 4.51(a). You observe that bulb 1 is twice as bright as bulb 2. Assuming that the brightness of a bulb is proportional to the power dissipated in the bulb’s resistor, which bulb’s resistor is larger, and by what factor? The bulbs are now connected in series ,as shown in Fig.4.51(b). Which bulb is brighter, and by what factor? How bright is each bulb...
The powers of two light-bulbs are 60 W and 125 W when connected in parallel across a 130-V source. What is the power of the bulb that will output less power when the two light-bulbs are connected in series with the same source?
The powers of two light-bulbs are 40 W and 115 W when connected in parallel across a 110-V source. What is the power of the bulb that will output less power when the two light-bulbs are connected in series with the same source?
