Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
In Fig. , the
battery has negligible internal
resistance and E = 48.0 V.
R1 = R2 = 4.00 Ω and
R4 = 3.00 Ω. What must the resistance
R3 be for the resistor network
to dissipate electrical energy at a
rate of 295 W?
