The current in a hair dryer measures 15.0 amps. The resistance of the hair dryer is 8 ohms. What is the voltage?
A. 120 V
B. 0.5 V
C. 7 V
D. 1800 V
I tried this and got D but it was wrong....can I get a little help on how to do this?
1. d 2.c 3.c 4.a 5. b 6.d 7.A 8.D 9. A 10.D

I would go for A. ;)
hobi is right !!
yes the answer is A
v=I*R=15*8=????
Thanks!!!!!
Yes, this is A
To find the voltage, we can use Ohm's Law, which states that voltage (V) is equal to current (I) multiplied by resistance (R). The formula is V = I * R.
In this case, the current is given as 15.0 amps and the resistance is given as 8 ohms. So, we can substitute these values into the formula to find the voltage:
V = 15.0 A * 8 Ī©
V = 120 V
Hence, the correct answer is A, 120 V.
