- Check Your Understanding Consider the electrical circuits in your home. Give at least two of circuits that must use a combination of series and parallel circuits to operate efficiently.arrow_forwardConsider the circuit below. The battery has an emf of = 30.00 V and an internal resistance of r = 1,00 . (a) Find the equivalent resistance of the circuit and the current out of the battery. (b) Find the current through each resistor, (c) Find die potential drop across each resistor, (d) Find the power dissipated by each resistor, (e) Find the total power supplied by the batteries.arrow_forwardCheck Your Understanding How would you use a river and two waterfalls to model a parallel configuration of two resistors? How does this analogy break down?arrow_forward
- Refer to Figure 10.17 and the discussion of lights dimming when a heavy appliance comes on. (a) Given the voltage source is 120 V, the wire resistance is 0.800 and the bulb is nominally 75.0 W, what power will the bulb dissipate if a total of 15.0 A passes through the wires when the motor comes on? Assume negligible change in bulb resistance, (b) What power is consumed by the motor?arrow_forwardUsing the exact exponential treatment, determine how much time is required to charge an initially uncharged 100-pF capacitor through a 75.0-MΩ resistor to 90.0% of its final voltage.arrow_forwardWhen two unknown resistors are connected in series with abattery, the battery delivers 225 W and carries a total currentof 5.00 A. For the same total current, 50.0 W is delivered whenthe resistors are connected in parallel. Determine the value ofeach resistor.arrow_forward
- Hi, here's my question. 26.60: In the figure, find the emf e in order for the current through the 7.00 W resistor to be 18.0 A. Each emf source has negligible internal resistance.arrow_forwardWhy should you not connect an ammeter directly across a voltage source as shown in Figure 21.51? (Note that script E in the figure stands for emf.)arrow_forwardCan a copper wire and an aluminum wire of the samelength have the same resistance? Explainarrow_forward
- Four identical batteries, each with an internal resistance Rw = 1 Ω and of unknown strengththe electromotive force is connected in parallel and the external resistance Rz = 6 Ω is supplied to them, on whichpower P1 = 6 W was released. Then the same four identical batteries were connected in series andthe same external resistance of Rz.Calculate the power P2 that will now be distributed on the external resistance Rzarrow_forwardSuppose a flashlight has 6.8 × 102 C of charge pass through it during time 0.35 h. A. What is the rate of the flashlight’s energy consumption, in watts, if it operates at a voltage of 3.00 V?arrow_forward
