-26.68 The figure shows a circuit containing two batteries and three resistors. The batteries provide Vemf 1 = 12.0 V and Vemf 2 = 16.0 V and have no internal resistance. The resistors have resistances of R1 = 30.0 32, R2 = 40.0 2, and R3 = 20.0 22. Find the magnitude of the potential drop across R2

A 12-volt battery is connected to two light bulbs, as drawn in
Figure 1. Light bulb 1 has resistance 3 ohms, while light bulb 2
has resistance 6 ohms. The battery has essentially no internal
resistance, and all the wires are essentially resistanceless,
too.
When a light bulb is unscrewed, no current flows through that
branch of the circuit. For instance, if light bulb 2 is unscrewed,
current flows only around the lower loop of the circuit, which
consists of...

The figure shows a small positive charge some distance away from a larger positive charge. The smaller charge is currently a distance rı away from the center of the larger charge, which is twice as far away as r2. Answer the three questions below, using three significant digits. Part A: What happens to the potential energy and the force if the smaller charge is moved to r2? Neither the force nor the potential energy change. Both the force and the...

A circuit is made of two 1.4 volt batteries and three light bulbs as shown in the figure. When the switch is closed and the buibs are glowing, bulb I hasa resistance of 11 ohms, bulb 2 has a resistance of 44 ohms, bulb 3 has a resistance of 26 ohms, and the copper connecting wires have negligible resistance. You can also neglect the internal resistance of the batteries (a) With the swtch open, indicate the approximate surface charge on...

The
circuit of the figure shows a capacitor, two ideal batteries, two
resistors, and a switch S. Initially S has been open for a long
time. If it is then closed for a long time, what is the change in
the charge on the capacitor? Assume C = 43 μF, 1 = 1.7 V, 2 = 6.0
V, R1 = 0.41 Ω, and R2 = 0.59 Ω.
