Alternating Current Of Rms Value 10 Is Passed Through 12 П‰ Resistance

An alternating current of rms value 10 A is passed through a 12 Ω resistance. The maximum potential difference … (c) 169.68 V (d)…

Answers:

The correct option  (c) 169.68 V

 Explanation:

I_rms = 10A

R = 12 Ω

∴ V_rms across resistor = I_rms × R

∴ V_rms = 10 × 12 = 120 V

Maximum potential difference across resistor is V_m = V_rms × √2

 ∴ V_m = 120 √2 = 169.7 V
