How much energy is extracted from an electron as it flows through a 9V battery from the positive to the negative terminal
A coil of 10H inductance and 5Ω resistance is connected in parallel with a 20Ω resistor across a 100-V DC supply which is suddenly disconnected. Find The voltage across the 20Ω resistor initially and after 0.3 sec.
You have a shortwave AM receiver (just an AM receiver that has the capability to receive signals in the FM frequency band) that receives an NBFM voice signal at some carrier frequency. You notice, however, that while the signal strength is maximiz..
