Answer to Question #111434 in Electric Circuits for alisa

Question

A 3 V battery is connected to a bulb with a resistance of 12 Ω. How much current will flow through the circuit?

Answer 1

$U=3$ V is the battery voltage

$R=12$ Ohm - resistance of the bulb

Current through the circuit can be found using Ohm's Law

$I={\frac U R}=0.25$ A
