The domestic electricity supply is alternating current. Instead of a steady flow of electrons through your appliances, there is a movement in one direction followed by a movement in the opposite direction. For heating and lighting, alternating current has exactly the same effect as a direct current. Devices like Transformers will only operate with alternating current.
Hertz measures the number of cycles of positive and negative current per second. In the USA, the standard frequency is 60Hz and in Europe it is 50Hz.
Now we come to the concepts of voltage and current. To understand the mains voltage, think in terms of electric pressure. The voltage is there whether you have anything plugged in or not. It rises to a maximum value, falls to zero then rises to a negative value and falls to zero again, all depending on the number of Hertz or cycles per second. For current, think in terms of the amount of electricity passing through the circuit per second. The amount of current that will flow depends on what you plug in. A lamp will draw a lot less current than a heater.
Hertz doesn't have a direct relationship to the amount of current. It is a measure of how frequently the current changes.

What relationship does Ohm's law express?
Ohm's law gives the relationship between current, voltage, and resistance. The law states that I=V/R, where I is current, V is voltage, and R is resistance. Source: university digital fundamentals
What is the relationship between resistance and current in a resistive circuit?
:) It's connected together
What is he relationship between voltage current and resistance called?
That is called Ohm's Law.
What is the relation between light and current?
One relationship is that both can flow in vacuum.
Why current frequency 50hz is not audible?
If your hearing is good, it should be. The human ear is generally said to pick up sounds between 20 - 20 000 Hertz.
What is volts per hertz ratio?
The volts per hertz ratio is a parameter used to characterize the relationship between the voltage and frequency of an alternating current system. It helps maintain a constant magnetic flux in motors and transformers under varying operating conditions. A balanced volts per hertz ratio ensures optimal performance and efficiency in electrical equipment.
Does dc current have hertz?
No, direct current (DC) does not have a frequency measured in hertz (Hz) because it flows in a single direction without changing polarity. Hertz is a unit of frequency typically used to describe alternating current (AC) that changes direction periodically.
What are hertz described as?
Hertz is the term meaning cycles per second. Household current in the US is 60 hertz.
Does dc have hertz?
No.
Why there is a relationship between current and voltage?
because current is the ratio of voltage and resistance.
The relationship between current assets and current liabilities is important in evaluating a company's?
Liquidity
What is the current relationship between US and Russia?
i think it is good !
Who discovered the relationship between the electric current and resistance?
This relationship was discovered by Karl Georg Ohm.
The relationship between current account balance and GDP?
The relationship between the current account balance and the GDP is that they both reflect the production in the given economy. They both deal with the net production.
What is the relationship between time charge and current?
Yes current = charge / time = I = Q/t
What is a sentence with the word hertz in it?
the radio signal was broadcast at 100 million hertz (megahertz).
The relationship between magnetism and electric current was discovered by?
Michael Faraday
