question 407

Multiple Choice

Solve the problem.
-Suppose that for an electrical appliance, voltage is given by $\mathrm { V } = 189 \sin 120 \pi \mathrm { t }$ and amperage by $\mathrm { I } = 1.07 \sin 120 \pi \mathrm { t }$ , where $\mathrm { t }$ is time in seconds. The wattage is given by $\mathrm { W } = \mathrm { VI }$ . Find the maximum wattage used by the appliance.

• A) \(404.46\)
• B) \(202.23\)
• C) \(101.115\)
• D) 189
