Question

A microwave at a potential difference of 120 V uses 50,000 J of energy during the 60 s it is on for? What is the current?

Answer 1

Given:

Voltage = 120 V

Time = 60 seconds

Energy consumed = 50,000 J

Let's find the current.

To find the current, apply the formula:

`I=(P)/(v)`

Where:

P is the electric power

V is the voltage

I is the current.

To find the electric power, we have:

`\begin{gathered} P=(J)/(t) \\ \\ P=(50000)/(60)=833.3\text{ W} \end{gathered}`

Now, to find the current, input values in the formula:

`\begin{gathered} I=(P)/(V) \\ \\ I=(833.3)/(120) \\ \\ I=6.9A \end{gathered}`

Therefore, the current is 6.9 amperes.

ANSWER:

6.9 Amperes
