In problems 1-5 I am having problems learning sign convention. Please solve these problems and go throught each circuit and please explain why you chose the signs. For example voltage source is say 12V, but sometimes its negative, sometimes positive, then when we reach an element signs change again. Please do problem 6 exp ...continues
Sign convention for power in electrical circuit
Please refer attachment.
In eehelp3 file or the CRT, book says or used negative signs, but one tutor says its positive. Who is right and why? In eehelp4 please make sure graphs are ok according to data, and with my sign convention problems what is energy absorbed, received, released....lost..how tie in with sign conventions etc and the circuit eleme ...continues

The figure to the left is a voltage source...
See diagram in attache file. --- The figure to the left is a voltage source The figure on top us a resistor(Ri ) but its part of the source. The figure to the right is a resistor ( R ) (outside the source) 1. What is the largest power that can be delivered to the load R? 2. What value of R achieves that?
The following circuit is left operating for a long time, until it reaches a DC steady state. (see diagram in the attached file) a) Determine the DC steady state values for i1, i2, and v3. b) Determine how much power the 24 V voltage source is supplying. c) Calculate how much energy is stored in the 4 micro farad capacit ...continues
current and voltage expressions of capacitor and inductor
(See attached file for full problem description) --- Problem 2. Current through 1uF capacitor is given as i(t) = 4 cos (wt) where w corresponds to the frequency of 1 MHz. What is the expression for the voltage on the capacitor? Problem 3. The same current i(t) = 4 cos (wt), at the frequency of 1 MHz, is flowing through ...continues
