Question
An electrical appliance has a resistance of 25 Ω. When this electrical appliance is connected to a 230 V supply line, the current passing through it will be:
(a) 0.92 A
(b) 2.9 A
(c) 9.2 A
(d) 92 A
Solution
(c) 9.2 A
Resistance = 25 Ω
Voltage = 230 V
Current = Voltage/Resistance
I = V/R
I = 230/25
I = 9.2 A
Thus, if an electrical appliance has a resistance of 25 Ω and when that electrical appliance is connected to a 230 V supply line, the current passing through it will be 9.2 A.
Is there an error in this question or solution?
Solution An Electrical Appliance Has a Resistance of 25 ω. When this Electrical Appliance is Connected to a 230 V Supply Line, the Current Passing Through It Will Be: (A) 0.92 a (B) 2.9 a (C) 9.2 a (D) 92 a Concept: Resistance of a System of Resistors - Resistors in Series.
