What is the meaning of RMS value?

The RMS value is the effective value of a varying voltage or current. It is the equivalent steady DC (constant) value which gives the same effect. For example, a lamp connected to a 6V RMS AC supply will shine with the same brightness when connected to a steady 6V DC supply.

What is meant by root mean square value of alternating current drive an expression for RMS value of AC?

Root mean square (r.m.s.) or virtual value of a.c.: It is that steady current, which when passed through a resistance for a given time will produce the same amount of heat as the alternating current does in the same resistance and in the same time. It is denoted. Irms or Iv.

What is mean value of alternating current?

Mean value of an alternating current is the total charge flown for one complete cycle divided by the time taken to complete the cycle i.e. time period T. The magnitude of an alternating current changes from time to time and its direction also reverses after every half cycle.

What is the RMS value of an alternating current find the relation between the RMS value and peak value of an alternating current that varies sinusoidally with time?

Therefore, the relationship between the peak and the rms value of current in an a.c. circuit is Irms=0.707I0.

What is the rms value of an alternating current find the relation between the rms value and peak value of an alternating current that varies sinusoidally with time?

What is root mean square RMS value of alternating current derive a relation between peak value and root mean square value of alternating current?

Irms = I0/√2 = 0.707I0 where I0 = peak value of alternating current.

What is meant by RMS value of current derive an expression for the RMS value of alternating current over a cycle ie T 0 Tot T?

Derivation of r.m.s. value of current: The alternating current changes continuously with time. Suppose, that the current through the resistance remains constant for an infinitesimally small time dt. = I02 R sin2 ωt dt.

What is meant by RMS value or effective value of an alternating current derive a relation between it and its peak value?

Therefore, the relationship between the peak and the rms value of current in an a.c. circuit is Irms=0.707I0. Note:Now, the peak value of current is defined as the maximum or highest value of current obtained in the one cycle.

What is RMS value of an alternating current find the relation between the RMS value and peak value of an?
