It depends what your voltage is and how much your electricity costs.
Assuming you are running standard residential voltage and your electricity costs 10 cents per kilowatt-hour. 1 Amp would cost you 1 cent per hour or 29 cents per day or $105 per year.
Electricity is not sold by the amp, but by the kilowatt. And the cost of a kilowatt varies depending on where you are. Sorry, but there is just no one answer to your question.
If you are asking about a Guitar Amp for example, you will have to look up the cost for what you want. If you are asking about an amp of current then you need to also know the voltage and power factor to determine Kilowatts per hour which is the unit used by power companies to calculate costs. A ballpark figure is 12 cents per Kilowatt Hour. If you are asking about a typical household with 120 VAC supply then 1 Amp x 120 VAC x 1 = 120 Watts. If you run the device for an hour then the "amp" at 12 cents per Kw Hr would cost you about 1.44 cents.
The average cost of electricity in Norway is around 1 NOK per kilowatt hour, but prices can vary depending on factors such as location, type of energy provider, and consumption patterns.
Using a 7 watt bulb for 1 hour would cost about 0.84 cents based on the average electricity rate in the United States. Over a year, if used for 4 hours a day, it would cost around $12.25 in electricity.
To calculate the cost of electricity for using a 1000-watt (1 kW) appliance for 12 hours, first determine the total energy consumed: 1 kW × 12 hours = 12 kWh. Then, multiply the total energy by your local electricity rate (e.g., $0.12 per kWh). For example, at $0.12 per kWh, the cost would be 12 kWh × $0.12 = $1.44.

The cost of 1 volt of electricity depends on your location and electricity provider. You would usually be charged for electricity by the kilowatt-hour (kWh), not by voltage. The cost of electricity can vary widely, so it is best to check your electricity bill or contact your provider for specific pricing.
A 1-amp adaptor can not be used for equipment that draws more than 1 amp. It is not clear from the question which part of your system is 12 v and which is 20 v.

The cost of 1 kilowatt-hour (kWh) of electricity can vary significantly depending on the region, provider, and time of year. In the U.S., the average cost typically ranges from about $0.10 to $0.30 per kWh. To find the exact rate for your location, it's best to check with your local utility company or your most recent electricity bill.

Refers to how much you pay for a unit of energy. When talking about natural gas, 1 unit = 1 CCF. When talking about electricity, 1 unit = 1 kiloWatt.
It costs [ 0.0005 x (power in watts used by the radio) x (cost of 1 KWh in your area) ]
The cost to produce 1 kWh of electricity from nuclear power can vary widely depending on factors such as operation and maintenance costs, initial construction costs, and fuel costs. On average, it can range from 3-6 cents per kWh.
The average cost of electricity in Norway is around 1 NOK per kilowatt hour, but prices can vary depending on factors such as location, type of energy provider, and consumption patterns.
1 amp = 1,000 milliamps so 1.5 amps = 1,500 milliamps
Most televisions today use around 100W when they are running. A typical charge for electricity is a little over 10c per kilowatt hour in the US or 10p in UK The television will use 1 KWH in about 10 hours so it will cost in the region of 1-2c or 1-2p per hour to run. The cost varies according to the size and consumption of the television and the cost of electricity in your region.
