Resistors and Ohm's Law Video Lessons

Concept

Problem: A toaster has a heating element of 15 Ω (ohms) and is connected to a 120 V (Volts) outlet. Show that the current drawn by the toaster is 8 A (Amps). You are asked to show the steps that calculate the current to be 8 amps.

FREE Expert Solution

In this problem, we're required to apply Ohm's law.

Ohm's law:

$\overline{){\mathbit{i}}{\mathbf{=}}\frac{\mathbf{V}}{\mathbf{R}}}$, where i is current, V is voltage, and R is resistance.
