Question
(a) All our household circuits are wired in parallel. Below is an example of a simple household circuit with 3 identical bulbs with resistance of100?each. Assume that this is the standard household120 Vcircuit. What is the current running through each bulb?
bulb 1 bulb 2 bulb 3 (a) All our household circuits are wired in parallel. Below is an example of a simple household circuit with 3 identical bulbs with resistance of100?each. Assume that this is the standard household120 V circuit. What is the current running through each bulb? bulb 1 bulb 2 bulb 3 (b) If bulb 2 in the circuit above blows out, as shown in the diagram below, what is the current running through each bulb now? bulb 1 bulb 3 (c) Why are household circuits wired in parallel? What would happen if your household was wired in series?Explanation / Answer
a)since three bulbs are identical
I1=I2=I3 =V/R =120/100=1.2A
b)I1=I3 =1.2A
C)in series voltage drop will be more across bulds,where as in a parallel circuit it will remain same across all the bulbs.
