:) thanks english is not a strong point of mine, thank you for the help, I am sure my calculater can add them but I am not sure how, so as long as it can convert between polar and rectangular and then do what i need to do il be happy, thank you.
well its 3 impedance in series and parallel so if i use the formula z =z1z2/z1 + z2 and am i right that in polar form you multiply the x-axis and add the y (i.e the value given as the angle)? that will sort the 2 impedances out in parallel then the remaining impedance will be in series with that...
Hello all i have a question about adding 3 impedances given in polar form, must i convert them to x..y.. first or is there a quicker way on a calculator and if so can anyone give advice i have the equation Zo=√Z(oc)Z(sc) but finding it hard to understand many thanks.
Hello all can anyone advise me if i am doing this right, i have a 3m bar supported at both ends at 1m in 5kn and 2m in 10 kn, i understood that moments A = 1x5 and 2x10 =25/3 and support A upward force 8.3kn and B 5+10-8.3 = 6.7kn? anyhelp would be great thanks
hello all new to the forum i have a calculus problem wonder if anyone can help the charge (q) can be obtained by intergrating (i) with respect to time determine the the charge on capacitor as a result of current flowing for three hundredths of a second if (i) is a constant 5mA, my calculus is...
