Problem

A 1.0 kW, 220 V metal-bodied toaster develops a fault that connects the live conductor to its casing. The casing is properly earthed through a resistance of 2 Ω. Neglect the resistance of the live conductor. What is the approximate current that flows through the earth connection during the fault? a) 4.5 A4.5\,\text{A} b) 78 A78\,\text{A} c) 110 A110\,\text{A} d) 11 A11\,\text{A}
