A light bulb is connected to two batteries. Each battery has 1.5V. If a student measures the current flowing through the light bulb to be 2 A, What is the resistance of the light bulb?

R = 0.75 ohms

Explanation:

Given that,

The voltage of each battery, V = 1.5 V

Current through the light bulb, I = 2 A

We need to find the resistance of the light bulb. We know that,

Ohm's law, V = IR

Where

R is the resistance of the light bulb

Put all the values,

So, the resistance of the light bulb is equal to 0.75 ohms.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
