In a combination circuit of 3 resistors R1 , R2 and R3 , R2 and R3 are in parallel on right and these two are then put in series with R1 on the left. The lower vertical lines represent emf of battery. If R1 on the left is 30 ohms and R2 = 20 ohms and R3 = 40 ohms and emf E= 12 volts, find The equivalent resistance of all 3 resistors The line current from the battery The voltage V1 across R1
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.
