Calculate the Current in a Simple Circuit

Anastasia's Simple Circuit Setup

Anastasia constructed a simple circuit with a battery and a light bulb. She knows that the resistance of the light bulb is 10Ω and that the voltage given to the light bulb is 12 V.

Calculating Current

Ohm's Law states that V = IR, where V is voltage, I is current, and R is resistance. To find the current flowing through the light bulb, we can rearrange the formula to I = V/R.

Plugging in the values we have:
I = 12 V / 10Ω
I = 1.2 A

Answer

Answer:

By calculating the current using Ohm's Law, the current flowing through the light bulb in Anastasia's circuit is 1.2 Amperes (A).

Question:

How can we find the current in a simple circuit with known voltage and resistance?

Answer:

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.
