A resistance R and inductance L and a capacitor C all are connected in series with an AC supply. The resistance of R is 16 ohm and for a given frequency, the inductive reactance of L is 24 ohm and capacitive reactance of C is 12 ohm . If the current in the circuit is 5 amp., find the potential difference across R , L and C .

Options

  1. A30,20,50 volt
  2. B40,100,60 volt
  3. C70,110,60 volt
  4. D80,120,60 volt

Correct answer

D. 80,120,60 volt

Step-by-step solution

V _ R = i R =5 16=80 Volt array l V _ L = i ( L )=5 24=120 Volt V _ C = i ( l / C )=5 12=60 Volt array
