Ac is sinusoidal? Tell me the meaning of this is whether the current in the wire is ~ (sinusoidal) ?

Question

In the cu wire used in house has 230v/15A. Tell me whether this cu wire current is moving like ~

Answer 1

sinusoidal is a refrence to the sine curve.
a sine curve, when graphed, fluxuates up and down- like a wave at sea.
AC current fluxuates between a posative and negative charge.
therefore, when its charge is graphed you get a curve. HOWEVER, THIS ISNOT A SINE CURVE.
because the shifts in polarity are nearly instantaneous-and polarity is either posative or negative (no partial this or that)- the graph looks like a bunch of squares. That is, a verticle line up, horizontal line over, verticle line down, a second horizontal line over (below the first).
but for all intents and purposes, the curve can be called sinusoidal, so yes the current in the wire is sinusoidal in respect to its alternating polarity.

Answer 2

hmmm.. you better ignore billy... he's working with too many computers. Household voltage/current is indeed sinusoidal in nature... 60 cycles/second in USA and 50 cycles/second in Europe... meaning that their values change in the shape of a sin-wave.... the reason for this shape is due to the electrical resistance, reluctance, and capacitance of the circuits used. Most governments have very strict guidlines on the frequency accuracy of electrical transmission lines and power companies are required by law to maintain with these guidlines.

Answer 3

Power supplied to domestic households is an AC si. wave that fluctuates to positive and negative values constantly.

All appliances like your toaster, TV etc. are designed to work on the AC power supply.

You Mobile charger, Laptop etc. require a DC which is why there is a converter called a RECTIFIER in the adaptor that converts the AC supply to a DC supply.

Answer 4

yes the power (both voltage and current) will be sinusoidal in nature.
But it wont be purely sinusoidal they will be distorted by the harmonics in the line
