alleryAn electric iron uses 1100 W at its higher setting on a 220 V supply. What current does it draw at this setting?
A0.2 A
B44 A
C1.5 A
D5 A
Answer & Solution
Correct answer: D. 5 A
1. Current from power and voltage: $I = \dfrac{P}{V}$.
2. Substitute $P = 1100$ W, $V = 220$ V: $I = \dfrac{1100}{220}$.
3. $I = 5$ A.
