Find the equivalent resistance between A and B
How does the resistance of a pure metal change if its temperature decreases?
If five resistances, each of value 0.2 ohm, are connected in series, what will be the resultant resistance?
Choose the correct alternative and rewrite the following:
You are given three equal resistances. In how many combinations can they are arranged?
Calculate the equivalent resistance between the points A and B for the following combination of resistors:
Three resistors of 6Ω, 3Ω and 2Ω are connected together so that their total resistance is greater than 6Ω but less than 8Ω Draw a diagram to show this arrangement and calculate its total resistance.
Six equal resistors of 1 ohm each are connected to form the sides of a hexagon ABCDEF. Calculate the resistance offered by the combination if the current enters at A and leaves it at D.
Illustrate-combination of cells e.g., three cells, in parallel, explaining the combination briefly. Obtain an expression for current ‘i’ in the combination.
The resistance of the hot filament of the bulb is about 10 times the cold resistance. What will be the resistance of 100 W-220 V lamps, when not in use?
