A 40-ohm resistor and a 60-ohm resistor are in parallel. In series with them are two other resistors of 20-ohm and 30-ohm. The whole combination is connected across a 1.5-V dry cell. What is the current in the dry cell?
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.
