why is fuse inserted in a series?
Asked by Sayantan Paul | 17 May, 2011, 04:20: AM
answered-by-expert Expert Answer
Fuse is always inserted in series with the switches / appliances, so that if the current exceeds its safe limit; the fuse would melt and break the circuit; hence protect the appliances.
