Hi. I've attached a circuit diagram. The schematic is for a dc power supply. It's purpose it to charge nicad batteries. However, we are having trouble locating the transformer. The transformer has been omitted, and the power is just represented by an AC power source. I'm a little unclear about the C-L-C portion of the
Hi. Can someone please walk me through how to do the following problem? An RC circuit consists of a resistor R = 32 ohms, a capacitor C = 2.5 micro-F, and an ac generator with an rms voltage of 120 V. At what frequency will the rms current in this circuit be 2.9 A? Thank you.
Hi. Can I get some help with understanding this conceptual question? Question: Why is the current in an ac circuit not always in phase with its voltage? Thank you.
Question: "Although an incandescent light bulb appears to shine with constant intensity, this is an artifact of the eye's persistence of vision. In fact, the intensity of a bulb's light rises and falls with time due to the alternating current used in household circuits. If you could perceive these oscillations, would you see the
An AC power generating station provides single phase power to a consumer 100 the generator end of the voltage at miles away, over a transmission line. The voltage at the consumer end of the line is 10KV. The consumer uses exactly 100K watts of power at the distant end. If the wire in the transmission line has a resistance of 0

The total current delivered to a number of devices connected in parallel is the sum of the individual currents in each device. Circuit breakers are resettable automatic switches that protect against a dangerously large total current by "opening" to stop the current at a specified safe value. A 1500 W toaster, a 1030 W iron, and
