Three resistors R1 = 10 Ω, R2 = 20 Ω, and R3 = 30 Ω are in series and are connected to a voltage supply that provides 15.3 V of voltage as shown in the circuit diagram below. Answer the following questions a) What is the total resistance of the three resistors? (b) What is the electric current at point A, B, C, and D? (c) What is the electrical potential difference between point B and point C in the circuit? (d) What is the electrical potential difference between point B and point D in the circuit? (e) Find the power dissipation in the resistor R1 when the voltage at the voltage supply is increased to 21 V.
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.
