This is a question about Kirchoff's rules. Consider the group of resistors shown in the attachment, where R1 = 4.0 ohms and E = 9.1 V. Find the current in each resistor. And determine the potential difference between points A and B. Please see attached for diagram.
We have a AC generator that is attached to a resistor with 500 kohms and a maximum voltage of 90 V. How do you calculate Imax, max power, avg power, rms current, rms voltage, and frequency.
A coil is connected to a 60 Hz, 100-v ac generator. At this frequency, the coil has an impedance of 10 omega and a reactance of 8 omega. (a) What is the current of the coil? (b) What is the phase angle between the current and the applied voltage? The current and voltage so that current and voltage are in phase? (c) What series
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 circuit
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

An ac circuit? 6) What is a
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
An AC generator consists of eight turns of wire, each of area .0756 m^2, and a total resistance of 8.38 Ohms. The loop rotates in the external magnetic field of strength .35 T at a constant frequency of 59.7 Hz. What is the maximum induced emf? Units if V What is the maximum induced current? Units of A
