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...

Two light bulbs are connected across the same amount of voltage. Their filaments are made of the same material and have the same length. But Bulb A’s filament has a cross sectional area that is twice that of Bulb B. Which bulb, if either, will be brighter? Explain your reasoning.

7. Two parallel conducting plates are connected to a constant voltage source. The magnitude of the electric field between the plates is 2,000 N/C. If the voltage is halved and the distance between the plates is reduced to 1/4 the original distance, the magnitude of the new electric field is (A) 8000 N/C (B) 1,600 N/C (C) 2,400 N/C (D) 4,000 N/C (E) 10,000 N/C 8. A parallel-plate capacitor is charged by connection to a battery. If the...

Review A circuit contains a source of constant voltage V and two resistors connected in parallel, as shown in (Figure 1). Resistor 1 has resistance R1, and resistor 2 has resistance R2. Part A Which two of the following statements are true? 1. The voltage source provides a constant voltage, a part of which, Vi, drops off across resistor 1, and the remainder, V2, across resistor 2. Hence V = V1 + V2. 2. The voltage drops V1 across resistor...
