Question
The resistance of a heater coil is 10 Ohms and the input voltage is 120V. What is the current?*2 pointsa. 12 ampsb. 1,200 ampsc. 0.083 amps
Solution
The current can be calculated using Ohm's Law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R). In this case, the voltage is 120V and the resistance is 10 Ohms.
So, I = V/R = 120V / 10 Ohms = 12 amps
So, the correct answer is a. 12 amps.
