what i did is used the division ratio an the current and the high voltage to find 2 resistors that will give that division ratio but remember if u put the auxillary circuit over the resistor which gives that 10V it will change the resistance thus i found the the new voltage across it then found...

I have attachted the question as a picture: my first attempt i calculated the voltage through the auxillary circuit to be 10V but i am confused of where the 0.5 A plays in this part, then i used nodal analysis to find the voltage input to the amplifier but up to that point i am confused of...

A conductor carrying a single electron directly in the centre meets a junction in which the the resistance are equal and are of 1 ohm, using knowledge of the various circuit characteristic laws, explain what would be the the potential across the branches since from my knowledge since the...

i am have been at this whole day can you tell me how to integrate 1/(x^2 +1)^2

how and where did you get 1/36

i don't understand part 2 can u explain what u did abit more

Given that z = 1/(3+it), it is denoted by T on a argand diagram 1. show that z + z* = 6zz* Got this part out but the next part i am totally confused I did abit of loci but i can't figure out this one 2. Show that if t varies T lies on a circle , and state the coordinates of the centre of the...
