Electric Circuits
Two collinear harmonic oscillations are made to superpose. If their displacements are represented as:
x1 = 2a cos t and x2 = 3a cos (t + )
Calculate the amplitude of the resultant oscillation when the phase difference is
(i) 2, (ii) 0, (iii) /2 and (iv) .

I calculated resistance value from resistor by colour code
I need to calculate voltage from it but I get two values i.e 4580ohms-5100ohms which value should i use to calculate voltage?
