Answer :
To find the resistance of the electric heater, you can use Ohm's Law, which states that the resistance (R) in a circuit is equal to the voltage (V) divided by the current (I). The formula for Ohm's Law is:
\[ R = \frac{V}{I} \]
Given:
- Current (I) = 12 A
- Voltage (V) = 120 V
1. Substitute the given values into the formula:
\[ R = \frac{120}{12} \]
2. Calculate the resistance:
\[ R = \frac{120}{12} = 10 \, \Omega \]
Therefore, the resistance of the electric heater is 10 ohms.
