Question

What is the electric power delivered to the 3.00 Ohm resistor in the circuit shown in the figure? A. 0.8 W B. 48.0 W C. 22.0 W D. 1.9 W E. 7.2 W The algebraic sum of all the potential differences around any closed circuit loop is A. Maximum because charges tend to move in the direction of maximum potential difference. B. Zero because the current must be completely used up after a closed loop due to charge conservation. C. Positive because charge will tend to accumulate at a node. D. Zero because of energy conservation. E. Negative because the charges must end up at the negative terminal of the battery. The capacitor in the figure is initially uncharged. At a time t after the switch S is closed the energy store capacitor has reached 25% of its maximum possible value. If R = 0.4 Ohm and epsilon = 12 V, what is the power resistor at this time? A. 15 W

Explanation / Answer

Algebraic sum of potential is zero because it is kirchoff's loop law which is based on conservation of energy hence option D.
