What is the role of fuse used in series with any electrical appliance ? Why should a fuse witha defined rating not be replaced by one with a large rating? |
| Answer» Solution :A fuseis a current-conducting wire made of puretin or of an alloy of copper and tin, has low RESISTANCE, and a low meltingpoint. A fuse is rated for EITHER 5 A or 15 A . When a currentmore than the rated value flows through it, the fuse wire melts and breaksthe circuit. Thus, it protects the appliances [with which it is connected in series] from getting damaged. If a fuse is REPLACED by one with larger RATINGS, the fuse does not burn off and the appliancesmay GET damaged. | |
