The voltage in a lightbulb is given by the equation V IR. In this equation V is the voltage I is the current and R is the resistance. What is the current in a lightbulb with a voltage of 10.0 V and a?

To find the current in a lightbulb using the equation ( V = IR ), you can rearrange it to ( I = \frac{V}{R} ). If the voltage ( V ) is 10.0 V, you would need the resistance ( R ) value to calculate the current ( I ). Once you have the resistance, simply divide 10.0 V by that resistance to find the current in amps.
