Kunlund 6.00 1 4.00 12 3. (10 pts) A 1.5V battery produces 45 mA when it is across a 30.0 2 load. (a) Find the potential difference across the battery's terminals. (b) What is the battery's internal resistance?
3. (10 pts) A 1.5 V battery produces 45 mA when it is across a 30.0 2 load. (a) Find the potential difference across the battery's terminals. (b) What is the battery's internal resistance? 4. (10 pts) See the figure below. In the plane of the paper, a particle of charge q -0.48 C moves with a speed of 93 m/s through a region where the magnetic field has a strength of 0.65 T. The velocity of the particle forms...
The voltage across the terminals of a 9.0V battery is 8.3V when the battery is connected to a 60? load. What is the battery's internal resistance?
The voltage across the terminals of a 9.0 V battery is 8.1 V when the battery is connected to a 40 Ω load. What is the battery's internal resistance?
When you connect an unknown resistor across the terminals of a 1.50 V AAA battery having negligible internal resistance, you measure a current of 17.2 mA flowing through it. What is the resistance of this resistor? If you now place the resistor across the terminals of a 12.4 V car battery having no internal resistance, how much current will flow? You now put the resistor across the terminals of an unknown battery of negligible internal resistance and measure a current of \(0.451\) A...
1)A 165 μF capacitor charged initially to 0.31 mC is connected across a resistor, and 2.0 s later its charge has dropped to 0.20 mC . Find the resistance. 2) A 380 Ω resistor and a 510 Ω resistor are in series. Part A When this combination is connected across a 12-V battery, the current is When this combination is connected across a 12- battery, the current is 22 mA . 130 mA . 13 mA . 37 mA ....
A real battery is not just an emf. We can model a real 1.5 V battery as a 1.5 V emf in series with a resistor known as the "internal resistance", as shown in the figure(Figure 1) . A typical battery has 1.0 Ω internal resistance due to imperfections that limit current through the battery. When there's no current through the battery, and thus no voltage drop across the internal resistance, the potential difference between its terminals is 1.5 V,...
When you connect an unknown resistor across the terminals of a 1.50V AAA battery having negligible internal resistance, you measure a current of 18.3mA flowing through it. What is the resistance of this resistor? If you now place the resistor across the terminals of a 12.9V car battery having no internal resistance, how much current will flow? You now put the resistor across the terminals of an unknown battery of negligible internal resistance and measure a current of 0.459A flowing...
A 50-Ω resistor is connected across a battery, and a 26-mA current flows. When the 50-Ω resistor is replaced with a 23-Ω resistor, a 43-mA current flows. A) What is the battery's voltage? B) What is internal resistance? I need the correct answers to 2 significant figures.
i need help with this page??? 1. (8 points total) A parallel plate capacitor whose plates have area A and plate separation d is connected to a battery. While the capacitor remiains connected to the battery, describe quantitatively what will happen to the charge on the capacitor if each if the following actions occur. That is, explain numerically how the magnitude of the charge on the capacitor in each circumstance compares to the original a. (3 pts) The distance between...
