It is given in the difficulty that the present in a hair dryer measures 15.0 amps. The resistance the the hair dryer is 8 ohms.

Calculate the value of voltage.

You are watching: The current in a hair dryer measures 15.0 amps

Put I= 15 A and also R= 8 ohms.

V= (15)(8)

V= 120 V

Therefore, the voltage is 120 V.

Keywords:

Hair dryer, current, resistance, voltage, Ohm"s Law

For this case we have that the current of a hair dryer is 15 Amps, if its resistance is 8 ohms. Lock ask united state to find the voltage the the hair dryer. We have that, through definition, Ohm"s law states that:

Where:

I: Is the current,R: that is the resistance,Substituting us have:

Thus, the voltage of the hair dryer is 120 volts.

Well the formula is V= i x R. (Voltage)=(Amps)x(Ohms)

So just plug that in! lol

15 x 8 =120

Hope this helps!

120 V.

Explanation:

From the question offered above, the following data were acquired from:

Current (I) = 15 A

Resistance (R) = 8 ohms.

Voltage (V) =.?

From Ohm"s law,

V = IR

Where:

V is the voltage.

I is the current.

R is the resistance.

With the above formula, us can attain the voltage as follow:

Current (I) = 15 A

Resistance (R) = 8 ohms.

Voltage (V) =.?

V = IR

V = 15 × 8

V = 120 V

Therefore, the voltage 120 V.
