Explanation

The Balance Sheet presents assets, liabilities, and equity at a specific date.

It gives a snapshot of the company’s financial health at that moment.

Explanation

When four equal resistors are connected in series, the total resistance (R_total) is:

R_total = 4R

The power dissipated (P) is:

P = V² / R_total

Given P = 10 W, we can rewrite the equation as:

10 = V² / (4R)

Now, if one resistor is connected across the same battery, the power dissipated (P') will be:

P' = V² / R

Comparing the two equations, we can see that:

P' = 4P

= 4 × 10 W

= 40 W
