6. An electrical circuit is shown below. The battery supplies 15 V. The resistances have the following values: R₁= 30 Ω, R₂ = 40 Ω, R3 = 20 Ω . (a) Calculate the replacement resistance of the three resistors. (b) Calculate the total current through the circuit, and the current through the respective resistor (c) If the lower right corner is grounded, then calculate the potentials at points A and B. (d) If the current is interrupted at point C, what will be the potentials at A and B.
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.
