In an operating electrical circuit the source of potential difference could be

An aluminium wire of 6.5metres long is connected in series with a copper wire 5 metre long. when a c voltage of 110 volts is connected accross the combination, it is found that the 65 volts is measured accros the aluminium wire. the diameter of the wite is 1mm. determine the diameter of the copper wire. resistivity of copper is 0.015 , that of aluminium is 0.023

In a fully DC circuit, sometimes Capacitors are installed in parallel with the load, what effect does this have on the signal

A 2.0 μF capacitor is charged by a 12V battery. It is disconnected from the battery and then connected to an uncharged 5.0 μF capacitor. Determine the total stored energy (a) before the two capacitors are connected and (b) after they are connected.

determine the value of load impedance (ZL) in order to get maximum power transfer at 100 Hz. What are the component values required to obtain this ZL?given that resistance is 200 ohm, inductance is 10mH.
