Question

Anastasia constructed a simple circuit with a battery and a light bulb. She knows that the resistance of the light bulb is 10

2 and that the voltage given to the light bulb is 12 V. What is the current through the light bulb?

Answer 1

Simple Single Loop Circuits. J. E σ. = ∆V = IR ... To find the current, use the total voltage and equivalent resistance: S. V ... A circuit contains a 48-V battery and two 240Ω light bulbs.
