In contrast, D.C. has higher power loss due to resistance.<\/h3>\n<\/li>\n<li>\n<h3>A.C. can be easily converted into high voltages for transmission over long distances, and then converted back into low voltages for household use.<\/h3>\n<\/li>\n<\/ul>\n<h3>(ii) The type of current used in household supply is alternating current (A.C.), which is different from the direct current (D.C.) given by a battery of dry cells. The key differences between the two types of current are as follows:<\/h3>\n<ul>\n<li>\n<h3>A.C. changes direction periodically, while D.C. flows in only one direction.<\/h3>\n<\/li>\n<li>\n<h3>The voltage of A.C. can be easily increased or decreased with the help of a transformer, while D.C. cannot.<\/h3>\n<\/li>\n<li>\n<h3>A.C. is more suitable for the long-distance transmission of power, while D.C. is more suitable for low-voltage applications.<\/h3>\n<\/li>\n<\/ul>\n<h3>(iii) An electric fuse prevents the electric circuit and appliances from possible damage due to short-circuiting or overloading by breaking the circuit when there is a current surge. The fuse contains a thin wire that melts when the current exceeds a safe limit, thereby breaking the circuit and preventing any damage to the appliances or the circuit. The fuse thus acts as a safety device by protecting the electrical appliances and the circuit from excessive currents.<\/h3>\n","protected":false},"excerpt":{"rendered":"<p>Question :(i) Why is an alternating current (A.C.) considered to be advantageous over a direct current (D.C.) for the long-distance transmission of electric power?
