A freezer of resistance 10.0 ΩΩ is connected to a 110. V source. What is the power delivered when this freezer is on?

An ideal battery has an emf of 14.3 V. If it is connected to a circuit and creates a current of 2.18A, what is the power delivered by the battery in units of Watts?

Three 85.0-w, 135-V lightbulbs are connected across a Av = 135-V power source, as shown in the figure below. Find the total power delivered to the three bulbs and the potential difference across each. Assume the resistance of each bulb is constant (even though, in reality, the resistance increases markedly with current). R1 AV R2 R3 (a) Find the total power delivered to the three bulbs. (b) Find the potential difference across each bulb. AVR. V = AVR2 V V

You connect five identical resistors in series to a battery whose EMF is 12.0 V and whose internal resistance is negligible. You measure the current that the circuit draws from the battery and find 0.719 A. What are the resistance of each resistor and the potential difference across each resistor? resistance: potential difference: V

What is the output voltage (in V) of a 3.0000 V lithium cell in a digital wristwatch that draws 0.340 mA, if the cell's internal resistance is 1.90 Ω?

18) A ball has a mass of 3 kg. It is connected to a spring that is displaced x = 0.5m away from its equilibrium length. The spring has spring constant k = 300N/m. Af- ter the spring is compressed, the ball rolls along a frictionless surface until it reaches an incline with an angle of 30•. What is the maximum height the ball reaches?
