Question

The electric mains in a house are marked 220V,50Hz. Write down the equation for instantaneous.​

Answer 1

Answer:

Answer:Hiiiiiiiii

Explanation:

Here,

Here,220 V is rms voltage. So peak voltage is 220√2V. =220√2sin(100πt+ϕ).

Here,220 V is rms voltage. So peak voltage is 220√2V. =220√2sin(100πt+ϕ).Make me brilliant.............

Answer 2

The equation for the alternating voltage is V = V0 sin ωt = V0 sin 2p f t. Where V is instantaneous voltage and V0 the peak value of the voltage. Here rms (virtual) voltage is Vrms = 220 V. Also f = 50 Hz. Substiuting values of V0 and f in eq.(i), we get V = 311 sin 100pt.
