The electric mains in the house are marked 220 V, 50Hz. Write down the equuation for instantaneous voltage.

  • 1

Equation for instantaneous voltage is V = 220 × √2 sin 2π (50)t = 311 sin 314t.

    1. The electric mains in a house marked 220 V and 50 Hz have an instantaneous voltage equation given by V =220√2 sin (2π(50)t) = 311sin(314t). Here, 311 V is the peak voltage, and 50 Hz is the frequency.
