Step 1
We are given the power (P) of the light bulb as 20 W and the current (I) as 2.4 A. We can use the formula: P = I^2 * R Where R is the resistance. We can rearrange the formula to solve for R: R = P / I^2 Now, we can plug in the given values: R = 20 W / (2.4 Show moreā¦

When a light bulb is connected across the terminals of a battery, the battery delivers 24 $\mathrm{W}$ of power to the bulb. A voltage of 11.8 $\mathrm{V}$ exists between the terminals of the battery, which has an internal resistance of 0.10$\Omega$ . What is the emf of the battery?
If a battery in a circuit is 24 volts and the resistance is 12 ohms what is the current
