Homework Statement
d.c supply 200V
capacitors A and B connected in series
p.d across A is 120V
p.d. across A, increased to 140V when a 3μF capacitor is connected in parallel with B.
Find capacitance of A and B.
Homework Equations
The only hint is the voltage drop (20V) across B when 3μF capacitor is connected in parallel with capacitor B. I have problem coming up with logical equations to solve this, can anyone help?
Capacitance total in parallel connection = sum of 'n' numbers of capacitors
Capacitance total in series connection for this case is = 1/Ct = 1/A + 1/(B+3)
