Ohm Exercise-1: Solution



In Brief

This page includes a solution to an exercise on Physics mentioned in to the previous section.
This helps learners to ensure their learning on aspects of physics in general but also how to Find the current drawn by an electric device in this case a shaver.

Question:

Assume you have a shaver with a heating element of 15 Ω and is connected to a 220-V outlet.
Find the current drawn by the shaver.

Solution:

Using the formula I = ε / R We obtain I = 220 V / 15 Ω = 14.66 A
