  • a)
    60 ohms
  • b)
    48 ohms
  • c)
    75 ohms
  • d)
    38 ohms
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Determine the resistance value of an appliance operating at 240V and ...
Power equation: P= V2/ R; P- Power consumption, V= operating voltage, R- Resistance
According to the question,
P= V2/ R or 1200 = (240 x 240)/ R
or R= 57600/ 1200
or R= 48 ohms

Determine the resistance value of an appliance operating at 240V and ...
Calculation:
- Given values:
Voltage (V) = 240V
Power (P) = 1200W

Formula:
Resistance (R) = (Voltage)^2 / Power

Substitute the values:
R = (240)^2 / 1200
R = 57600 / 1200
R = 48 ohms
Therefore, the resistance value of the appliance operating at 240V and consuming power of 1200 Watts is 48 ohms.

Correct Answer:
b) 48 ohms
