The current in a hair dryer measures 11 amps. The resistance of the hair dryer is 12 ohms. What is the voltage?
Valentin [98]

Voltage is given by the formula

V = IR (Ohms law)

where V is the Voltage

I is the current

and R is the Resistance

Here it is given that the current is I=11

Resistance is R =12

so plugging this in the formula

V = IR

V= 11 * 12

V= 132 Volts

So the Voltage for the given dryer is 132 Volts

Hypothesis:
SIZIF [17.4K]

Answer:

1.) Wavelength

2.) Number of fringes

Explanation:

1.) If we split a laser beam by using a diffraction grating slide, then we can

verify the wavelength by applying the formula λ​ = ds/l.

2) If we split light into its individual wavelengths using a diffraction grating,

then we can determine the number of fringes by multiplying the spacing of the gradient lines (d) times the distance to the central maxima of the color band (s) divided by the length distance from the grating slide to the screen (l).​
