Answer:

120 V.

Step-by-step explanation:

From the question given above, the following data were obtained 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, we can obtain 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.
