Can someone check this Circuits worksheet for me?

i glanced really fast, but do you have 2 different current values for the two resistors that are in series? (the 100 and 200) i seen .05 and .1

anonymous · Answer

i can see your first one is not right. are you familiar with kirchoffs laws? KVL in particular?

Agree first is wrong I did not look further at No. 1, but one error you show equal voltage drops across two series resistors of different value.

radar · Answer

No 2 also has errors, you depict voltage drops of 150 volts each across two series resistors this adds up to 300 volts which  exceeds the applied voltage, plus different values of current in two resistors which are in series.

radar · Answer

The last one has errors also, The total resistance I believe is 110 Ohms, therefore the 9 volt battery is producing a current of 9/110 or 0.0818181818 amp not the value of .0018 A which you are indicating.
