Resistance (R) = <u>9.375 ohm (Ω)</u>

Steps:

R =   \frac{V}{I}

=    \frac{12 \: volt}{1280 \:  milliampere}

=  \frac{12 \: volt}{1.28 \: ampare}

= 9.375 \: ohm (Ω)

A toaster oven uses 65,000 joules of energy in 40sec to toast a piece of bread. What is the power of the oven?
storchak [24]

Answer:

Power = 1625 Watts

Explanation:

Given the following data;

Energy = 65,000 J

Time = 40secs

To find the power;

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

Power = \frac {Energy}{time}

Substituting into the equation, we have

Power = 65,000/40

Power = 1625 Watts
