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.
Three resistors with resistances R1 = R/2 and R2 = R3 = R are connected as shown, and a potential difference of 240 V is applied across terminals a and b (see figure below).
(a) If the resistor R1 dissipates 85.0 W of power, what is the value of R?
Ω
(b) What is the total power supplied to the circuit by the emf?
W
(c) What is the potential difference across each of the three resistors?
