Question

What is the voltage across an electric hot plate which draws 10A from the line when its hot resistance is 22 Ω?

a. 2.2 V
b. 10 V
c. 22 V
d. 220 V

Answer 1

The voltage across the electric hot plate is 220 V.

Step-by-step explanation:

To find the voltage across the electric hot plate, you can use Ohm's Law which states that V (voltage) is equal to I (current) multiplied by R (resistance). In this case, the hot resistance of the hot plate is given as 22 Ω and it draws a current of 10A. Therefore, the voltage across the hot plate can be calculated as:

V = I * R

V = 10A * 22 Ω

V = 220V

So, the correct answer is d. 220 V.
