How does current travel if disconnected from a voltage source part of RL circuit?
When the switch is in position 1 the LEDs are both off as they are reverse polarised. When switching to the 2 position, both LEDs will flash. In this way you can immediately understand what the direct …

How to calculate current sharing between two different voltage souces in a parallel circuit?
The alternator voltage is rectified obtaining a double half-wave which is then capacitively filtered so the resulting voltage is composed of a direct component plus a ripple. Assuming that the voltage …

Amplifier based on a bipolar transistor with a common emitter
Try with the values calculated with my method. The voltage gain, not being known, was set to my liking (I apologize, there are some overlaps in the printout that disturb the reading):

Problem 3.15 from Hyat: Engineering Circuit Analysis
The two independent current generators are equivalent to a single generator with current delivered equal to the algebraic sum of each current. … The direction of the resulting current is the same as that which has a greater value. …

Can we find the equivalent resistance just by using series and parallel combinations?
(the negative signs indicate that the current or voltage is opposite to that chosen in the digraph, for this reason the ratios can be negative, at least until proven otherwise): …

How to determine the directions of voltages across resistors in circuit diagrams?
First of all, it is necessary to draw the oriented graph of the network, clearly highlighting the numbered nodes; the reference node is generally indicated with the number 0. If n is the number of nod …
