PHY 212 Bonus Question for Exam #4 1. In the circuit shown in the diagram, the current in the solenoid (opening is perpendicular to the plane of the page) is in the direction shown (counterclockwise). The current is INCREASING linearly in time. The battery in the circuit has an emf equal to the emf of a single loop around the solenoid. The bulbs are all identical and the internal resistance of the battery is much less than the resistance of...
Circuit Analysis in Electrical Engineering 4. A resistor and a capacitor are connected in series across a 270-V ac supply. When the frequency is 40 Hz, the current flowing in the circuit is 6.25 A. When the frequency is 50 Hz, the current flowing in the circuit is 7.5 A Calculate the resistance and capacitance of the resistor and capacitor respectively.

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...
