As an expert in the field of electrical engineering, I can provide you with a comprehensive answer to your question about the type of electricity in your house. It's important to understand the fundamental differences between AC (alternating current) and DC (direct current) before we delve into the specifics of household electricity.
AC is the type of electrical current that periodically reverses direction. It's the standard for residential electrical systems in many countries, including the United States, Canada, parts of Europe, and Australia. The primary reason for AC's prevalence is its ability to be easily transformed to different voltages, making it more efficient for long-distance transmission and safer for household use.
DC, on the other hand, is a type of current that flows in a constant direction. Historically, DC was the first form of electricity to be used in homes, but it has since been largely replaced by AC for the reasons mentioned above. However, DC is still used in certain applications within the home, such as in batteries and some electronic devices.
Now, regarding the electricity in your house, it is most likely AC. Here's why:
1. Transmission Efficiency: AC can be transmitted over long distances with less loss of energy compared to DC. This is due to the ability to use transformers to step up the voltage for transmission and then step it down for household use.
2. Safety: AC systems are considered safer because they do not require the high voltages that DC systems do for the same power transfer, reducing the risk of electric shock.
3. Standardization: AC has become the standard for residential electricity in many parts of the world, which means that most electrical appliances and installations are designed to work with AC power.
4. Infrastructure: The existing electrical grid and infrastructure are predominantly based on AC, making it more practical and cost-effective to continue using AC for residential electricity.
5. Historical Use: While the historical context you provided mentions that many combinations of voltage and utility frequency were used in the past, the modern electrical grid has standardized on AC for the reasons listed above.
It's worth noting that within your home, you may find a mix of AC and DC. For example, the electricity coming from the wall outlets is AC, but the power supplied to devices like smartphones and laptops is often DC, which is converted from AC using an adapter or charger.
In summary, while DC was used in the past, the electricity in your house is almost certainly AC due to the advantages it offers in terms of transmission efficiency, safety, and compatibility with modern electrical appliances. The historical use of DC has been almost completely displaced by AC in public power systems, but there are still niche applications where DC is used, particularly within electronic devices.

Many other combinations of voltage and utility frequency were formerly used, with frequencies between 25 Hz and 133 Hz and voltages from 100 V to 250 V. Direct current (DC) has been almost completely displaced by alternating current (AC) in public power systems, but DC was used especially in some city areas to the end ...
