A 110 V d.c source replace an a.c source such that heat produced is same in the two case. What is the rms value of alternting voltage source.

A 110 V d.c. heater is used on an a.c. source, such that the heat produced is the same. What would be the r.m.s. value of the alternating voltage?

Name one d.c. source and one a.c. source.

A 110 V d.c. heater is used on an a.c source such that the heat produced is same as it produces when connected to 110 V dc in same time -intevals. What would be the r.m.s. value of the alternating voltage?

Assertion : An electric bulb is first connected to a dc source and then to a ac source having the same brightness in both the cases. Reason : The peak value of voltage for an A.C. source is sqrt(2) times the root mean square voltage.

The instantaneous emf an a.c. source is given by epsi=300 sin 314 t . What is the rms value of the emf?

Peak value of emf of ac source is E. What is its rms value?
