How to Calculate Voltage, Current, & Resistance? | Ohm's Law | Practice Examples | Physics

Learn how to calculate current, voltage, and resistance using Ohm's law with practice examples.

In this video, I will show you how to solve Ohm's law practice problems.

The formula to solve for current, voltage, and resistance is V = I x R

Current (I) = number of electrons (measured in amps)
Voltage (V) = how much energy a charged particle carries (measured in volts)
Resistance (R) = depends on the type of conductor being used (measured in amps)

There are 4 steps to calculate current, voltage, and resistance using Ohm's law.

Step 1: write down the known values, given in the question

Step 2: write down the unknown value, something that we need to solve for

Step 3: write down the Ohm's law formula ( V = I x R ) and manipulate the formula to isolate the variable we need to solve for

Step 4: plug in the values given in the question and solve for the answer.
