In the following circuit, the battery has an emf of 2 V and an internal resistance of 2/3 Ω. The power consumption in the entire circuit is _________ W. Numerical answer type. Work it out, then open the answer.

Answer: 3. The left side of the square is one node and the right side the other. Top 2 Ω, bottom 2 Ω and the two diagonals (together 2 Ω) are in parallel: R = 2/3 Ω. I = (2)/(2/3 + 2/3) = 1.5 A. Total power P = EI = 2 × 1.5 = 3 W.

Electrical Power & Heating Effect

In the following circuit, the battery has an emf of $2\text{ V}$ and an internal resistance of $\frac{2}{3}\ \Omega$ . The power consumption in the entire circuit is _________ W.

Numerical answer type. Work it out, then open the answer.

Show answer and solution

Answer: 3

The left side of the square is one node and the right side the other.
Top $2\ \Omega$ , bottom $2\ \Omega$ and the two diagonals (together $2\ \Omega$ ) are in parallel: $R = 2/3\ \Omega$ .
$I = \dfrac{2}{2/3 + 2/3} = 1.5\text{ A}$ .
Total power $P = EI = 2 \times 1.5 = 3\text{ W}$ .
