Resistances in Parallel

Resistances in Parallel Figure 28.-8a shows three resistances connected in parallel to an ideal battery of emf . The term “in parallel” means that the resistances are directly wired together on one side and directly wired together on the other side, and that a  potential difference V is applied across the pair of connected sides. Thus, all three …

Multiloop Circuits

Multiloop Circuits assume the batteries are ideal. There are two junctions in this circuit, at b and d, and there are three branches connecting these junctions. The branches are the left branch (bad), the right branch (bad), and the central branch (bd). What are the currents in the three branches? We arbitrarily label the currents, using a different …

The electrical field electrons lurks in rivers of South America, killing the fish on which it preys with pulses  current. It does so by producing a potential difference of several hundred vol,ts along its length  the result current he surrounding er, from near the eel’s head e tail region, can be ash as one ampere. If …
