Q1. Scenario: A small fan motor of effective resistance 1100 ohm runs on the 220 V household mains supply. Question: What is the rated power consumption of the appliance (watts)?
- A.44 W
- B.242000 W
- C.5 W
- D.1320 W
Answer: A. 44 W
Q2. Scenario: An electric mixer of effective resistance 484 ohm draws power from the 220 V mains during cooking. Question: What is the rated power consumption of the appliance (watts)?
- A.2.2 W
- B.704 W
- C.100 W
- D.106480 W
Answer: C. 100 W
Given 484 ohm, 220 V, asked for What is the rated power consumption of the appliance (watts)?. By hence the answer = 100 W. hence the answer = 100 W. an ionic bond forms when a metal donates electrons to a non-metal: e.g. Thus option C) 100 W. Others fail: option A) '2.2 W' is incorrect: Inverted ratio; P = V^2/R, not R/V; option B) '704 W' fails since Adding V and R is dimensionally wrong; use P = V^2/R.
Q3. Scenario: A clothes dryer with effective resistance 880 ohm runs on 220 V mains. Question: What is the rated power consumption of the appliance (watts)?
- A.4 W
- B.55 W
- C.1100 W
- D.193600 W
Answer: B. 55 W
Given 880 ohm, 220 V, asked for What is the rated power consumption of the appliance (watts)?. By hence the answer = 55 W. hence the answer = 55 W. an ionic bond forms when a metal donates electrons to a non-metal: e.g. Hence option B) 55 W. Others fail: option A) '4 W' doesn't hold - Inverted ratio; P = V^2/R, not R/V; option C) '1100 W' fails since Adding V and R is dimensionally wrong; use P = V^2/R.
