A series circuit consists of a resistance of 4 ohms, an inductance of 500mH and a variable capacitance connected across a 100V,50Hz supply. Calculate the capacitance require to produce a series resonance condition and the voltage generated across both the inductor and the capacitor at the point of resistance.
. At resonance
ωL=1/ωC and I=U/R.
So, we have
C=1/(ω^2 L)=1/((2π∙50)^2∙500∙〖10〗^(-3) )=2.03∙〖10〗^(-5) F.
