3000 cells of electricity passed through the spiral of the hotplate in 12 minutes. What is the current in the spiral?

Given:

E = 3000 Pendant – the amount of electricity that passed through the spiral of the electric stove;

t = 12 minutes – time span.

It is required to determine the current strength I (Ampere) in the spiral of the electric stove.

Let’s convert units of time from minutes to seconds:

t = 12 minutes = 12 * 60 = 720 seconds.

Then the current strength in the spiral of the electric stove will be equal to:

I = E / t = 3000/720 = 4.2 Amperes.

Answer: the current strength in the spiral of the electric stove is 4.2 Amperes.
