Hi  there

I need help with the June 09 paper 2 part 1 question 5 b.I don't understand how we get 2 minimas.Can anyone help plz?

thanks ! :)

halosh92:
i have  a question
to calculate the power dissipated, in a series circuit and in a parallel circuit what do we do
do we just add up the powers?

nid404:
didn't get you.

give an example?

like if we have a circuit with two loops
first loop contains 2 resistors
and second loop contains 1 resistor
each has powers of 2W
how do we calculate the total power......for only the 1st loop
and the total power  for the whole circuit.
