The four resistances are R1 = 1 ?, R2 = 2 ?, R3 = 4 ?, and R4 = 12?. The power source has a potential difference V = 12 V. (a) Find the equivalent resistance of the circuit. (b) What is the value of the current I in the circuit? (c) Find the currents in R3 and R4.
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.
