Answer:
c
10 A
Step-by-step explanation:
Use the equation that calculates voltage: V = IR (That's capital "i")
"V" represents voltage. It's measured in the unit volts, the symbol V.
"I" represents current. It's measured in amperes, the symbol A.
"R" represents resistance. It's measured in ohms, the symbol Ω.
From the question, we know the source is 120 V and the resistance is 12Ω.
Substitute V = 120V, R = 12Ω into the equations. Isolate "I" to find the current.
V = (I)(R)
120V = (I)(12Ω)
I = 120V ÷ 12Ω
I = 10A
Therefore:
The current of a 12-ohm hair dryer that is connected to a 120-volt power source is 10 A (10-amps).
