The heating element of a clothes dryer has a resistance of 14 and is connected across a 240 V outlet. What is the current in the heating element?
"has a resistance of 14"
Units?? ohms?
use V=IR (Ohm's law)
The heating element of a clothes dryer has a resistance of 14 and is connected across a 240 V outlet. What is the current in the heating element?
To determine the current in the heating element, we can use Ohm's law, which states that the current (I) flowing through a device is equal to the voltage (V) across the device divided by its resistance (R).
Mathematically, this can be represented as:
I = V / R
In this case, we are given that the resistance of the heating element is 14 and the voltage across it is 240 V. Plugging these values into the formula, we have:
I = 240 V / 14
Calculating this gives us:
I = 17.14 A
Therefore, the current flowing through the heating element is approximately 17.14 Amperes.
