Electric field lines run from positive charges to negative charges. They originate from positive charges and terminate on negative charges. The density of the field lines is proportional to the strength of the electric field at a particular point. The direction of the electric field lines indicates the direction of the force that a positive test charge would experience if placed in the field. **

No, there should not be a small electric shock when you pet your cat. If you are experiencing a small electric shock when petting your cat, it could be due to static electricity buildup in your environment.

The term for an electric central heating system from the 1980s is "electric storage heating." This type of heating system used off-peak electricity to heat up bricks or other storage materials during the night, which would then release heat gradually throughout the day. It was a popular choice for electric heating in the 1980s due to its energy efficiency and cost-effectiveness. **

The central bank interest rate, also known as the policy rate, is set by the central bank to influence the overall economy. It is the rate at which commercial banks can borrow money from the central bank. On the other hand, the market interest rate is determined by the supply and demand for credit in the financial markets. It is the rate at which individuals and businesses can borrow money from commercial banks or other financial institutions. The central bank interest rate serves as a benchmark for the market interest rate, but the market interest rate can fluctuate based on various factors such as inflation, economic conditions, and risk. **

Yes, there are several affordable electric cars currently available on the new car market. Models such as the Nissan Leaf, Hyundai Kona Electric, and Chevrolet Bolt EV offer relatively lower prices compared to other electric vehicles. These cars also qualify for federal tax incentives, making them even more affordable for consumers. As technology advances and more automakers enter the electric vehicle market, we can expect to see even more affordable options in the future. **
