- parallel combination of resistors and its applications in daily life
Shaalaa.com | Electricity part 8 (Resistor Parallel & series)
Two resistors having resistance 4𝛀 and 6𝛀 are connected in parallel. Find their equivalent resistance.
MULTIPLE CHOICE TYPE:
In parallel combination of resistances:
(a) p.d is same across each resistance
(b) total resistance is increased
(c) current is same in each resistance
(d) all above are true
Calculate the equivalent resistance of the following combination of resistors r1, r2, r3 and r4 if `r_1=r_2=r_3=r_4=2.0Ω ` between the points A and B in Fig. 8.42
A combination consists of three resistors in series. Four similar sets are connected in parallel. If the resistance of each resistor is 2 ohm, find the resistance of the combination.
You have three resistors of values 2Ω, 3Ω and 5Ω. How will you join them so that the total resistance is less than 1Ω? Draw diagram and find the total resistance.
Three resistors each of 2Ω are connected together so that their total resistance is 3Ω. Draw a diagram to show this arrangement and check it by calculation.
