Question

Define average or mean value of A.C. and hence find the relation between average value and peak

value of an alternating signal.

ii) An alternating e.m.f. e = 300 sin (100πt) volt is applied to a pure resistance of 100 ohm. Calculate

r.m.s current through the circuit.​

Answer 1

total number of observation by number of observation it is average

Answer 2

Explanation:

Given An alternating e.m.f. E = 300 sin (100πt) volt is applied to a pure resistance of 100 ohm. Calculate r.m.s current through the circuit.

• So the equation of e.m.f is E = 300 sin (100 πt)
• Now peak emf is 300 volts
• So rms will be Vrms = Vo / √2
•                                  = 300 / √2
•                                    = 212.16 volts
• Now the resistance is given as R = 100 ohms
•                        Now I = V/R
• Therefore the rms current  Irms = Vrms / R
•                                                   = 212.16 / 100
•                                                    = 2.1216 A
