An oven has two 36 ohm elements connected in parallel with 240 V applied. Calculate the power drawn as it operates.

Select one:
A. 200 W
B. 1601 W
C. 799 W
D. 3192 W

Answer :

The correct answer is option (d) 3192 W.

Given that an oven has two 36-ohm elements connected in parallel and 240 V applied. We need to calculate the power drawn as it operates.

The formula to calculate the power consumed in an electrical circuit is given by

P = V2/R where

P = power,

V = voltage,

and R = resistance

Here, the resistance of one 36 ohm element, R = 36 ohm

Total resistance when two 36 ohm elements are connected in parallel = R/2 = 18 ohm

Voltage, V = 240 V

Putting the values in the formula, we get

P = V2/R

= (240)2/18

= 3200 W

Therefore, the power drawn by the oven as it operates is 3200 W or 3.2 kW.
