R-40

REQ

R₁ = 802

R-40

R = 80

Calculate:

(a) the current

(2)

(d) the net power

Step By Step Answers with Explanation

4. Calculate the rates of energy conversion and energy dissipation in the battery.

5. Calculate the net power.

• Req is the equivalent resistance

• R1, R2, and R3 are the resistances of the individual resistors

The total current flowing through the circuit is calculated using the following formula:

I = V / Req

Substituting the values of the voltage source and the equivalent resistance, we get:

I = 12 / 24

The rate of energy conversion in the battery is the product of the voltage and the current. The rate of energy dissipation in the battery is the product of the square of the current and the equivalent resistance.

The rate of energy conversion in the battery is:

P = I^2 * Req

P = 0.5^2 * 24

Pnet = 6 - 6

Pnet = 0 watts
