What is the potential drop across each of the resistors?
What is the potential drop across each of the resistors?
Ohm’s law is used once more to determine the current values for each resistor – it is simply the voltage drop across each resistor (60 Volts) divided by the resistance of each resistor (given in the problem statement).
What is the potential difference across the 4 ohm resistor?

How are three resistors connected?
Answer: To obtain a combined resistance of 9 ohms, three resistors each of resistance 6 ohm should be connected in a parallel circuit and one in series. In a parallel circuit, the equivalent resistance of all the resistors connected is equal to the reciprocal value of the sum of the individual resistances.
What is the highest and lowest resistance?
(a) The highest resistance is when the resistances are connected in series. Hence, the highest resistance is 48 Ω. Hence, the lowest resistance is 2 Ω.
How will you connect three resistors of 2 ohm 3 ohm and 6 ohm?
1 Answer. (a) In order to obtain a total resistance of 4 Ω from three resistors of 2 Ω, 3 Ω and 6 Ω Firstly, connect the two resistors of 3Ω and 6Ω in parallel to get a total resistance of 2Ω which is less than the lowest individual resistance.
What is the resistance between A and B in the figure given below?
Therefore, resultant resistance = 18.75 + 10 + 10 = 38.75 ohms.
What is the effective resistance between A and B?
Therefore, equivalent resistance across AB is 5R12. Hence, option (C) 5R12 is the correct option.
What is the resistance from A to B?
In simpler terms : Voltage remains same until a resistance comes in it’s way ! Here also same, So basically those three resistances are parralel to each other between A and B, Since all are same and 3 are present Equivalent resistance is R/3 !!
How do you find the equivalent resistance between A and B?
Calculate the equivalent resistances between the points AandB of the circuits shown in (fig. 2.33)(b). Further, R1(=24Ω)and6Ω are in parallel between the points AandB. Thus, effective resistance between AandB, i.e., R=24×624+6Ω=4.8Ω.
