How do you calculate voltage drop across a resistor?

Answer 1

Leo Abeyta

#V_"drop"=IR#

where, #I#, is the current (in Amperes) through the resistor and, #R#, is the value of the resistor (in Ohms).

You can calculate the voltage drop across a resistor using Ohm's law, which states that voltage ((V)) equals current ((I)) multiplied by resistance ((R)). Mathematically, (V = IR). So, to calculate voltage drop across a resistor, you multiply the current flowing through the resistor by its resistance.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
