- Two resistors with resistances of 4.5 ohms and 4.5 ohms are connected in parallel to a 3.0 volt battery. What is the current that flows through the battery?Two resistors with values of 13 Ω and 36 Ω, respectively, are connected in parallel and hooked to a 17 V battery. What would be the current in the circuit? What would be the power expended in the circuit?Which of the following would increase the flow rate of electrons in a wire? Select all that apply Increasing the voltage from 3 V to 6 V Decreasing the voltage from 6 V to 3 V Decreasing the resistance from 4 ohms to 2 ohms Increasing the resistance from 2 ohms to 4 ohms
- When a battery “dies” the resistance inside the battery rises while the voltage it can produce almost always remains the same. A new 1.5 volt alkaline battery has a resistance of 0.15 ohms. An older battery may have a resistance of 15 ohms. How much current is drawn by a new battery?Sketch a diagram indicating how a voltmeter would be wired into a circuit of a battery and one bulb in order to measure the voltage drop across the bulb.Define resistivity as a material property.
