this is the problem, there are 4 resistors in a series circuit, and the total power is 20W. one resistor burns out( which should mean that there should zero current or voltage running through the circuit, so I think they mean a short circuit) anyway, what is the power dissipated by the remaining resistors?
now the answer is suppose to be 8.9W. but the only way I could get this answer is by dividing 20W by 3( which is 6.67W per resistor) and then adding the 6.67W to 20W and then dividing by 3 again. hence 8.9W dissipated per resistor.( rounded up)
this is not making much sense to me. is the answer wrong or I am I just missing some little detail here.
any help would be appreciated.
