Example Question #12 : Calculating Total Resistance
There are three resistors in parallel in a circuit with resistances of , , and .
What is the equivalent resistance?
The equation for resistors in parallel is:
We are given the values of the resistors. Using this formula, we can solve for the equivalent resistance.
Plug in the given values and solve.
Example Question #1 : Electricity And Magnetism
A voltage of applied between the ends of a wire results in a current of . What is the resistance of the wire?
This question can be solved using Ohm's law:
We are given the voltage and the current. Using these values, we can solve for the resistance.
