plzz give the formuale not the final answer

Answer 4

kindly help me on que 1 my value are: The elements in this circuit have the following values: R1=50Ω, R2=50Ω, R3=100Ω, V1=4V, I1=0.0001A and I2=0.001A

Answer 5

once i get the formula i'll just plug # in

Answer 6

thats the answer for Q4

Answer 8

@pauliusn how did you get these answers? Could you explain/post formula?

Answer 9

pauliusn...is those the answer for engr question if so what the formula

Answer 10

can u tell me the formulae for them @pauliusn

Answer 11

One way is very simple. Just use Circuit Sandbox . There place the your circuit wit own values of components, and then you will get A and B points voltages. And then calculate power is easy.
Power on R1 is (V1-A)^2/R1;
Power on R2 is (A-B)^2/R2;
If R1=R2 - power on these resistors is equal..
Power on R3 is B^2/R3;
Power from V1: calculated current from V1*V1
Power from I1: B*I1
Power from I2: -B*I2

Something like that..
This is the very easy way.
Another way is to use node calculation mode. And then get A and B voltages and then all calculations.
