How many 176 Ω resistors (in parallel) are required to carry 5 A on a 220 V line?
You are given three resistances of 1, 2 and 3 ohms. Shows by diagrams, how with the help of these resistances you can get:
(i) 6 Ω
(ii) `6/1` Ω
(iii) 1.5 Ω
Four resistors each of resistance 2Ω are connected in parallel. What is the effective resistance?
A uniform wire with a resistance of 27 Ω is divided into three equal pieces and then they are joined in parallel. Find the equivalent resistance of the parallel combination.
Two devices are connected between two points say A and B in parallel. The physical quantity that will remain the same between the two points is:
The least resistance obtained by using 2 Ω, 4 Ω, 1 Ω and 100 Ω is:
A coil in the heater consumes power P on passing current. If it is cut into halves and joined in parallel, it will consume power:
Assertion: When a battery is short circuited, the terminal voltage is zero.
Reason: In a short circuit, the current is zero.
Four resistors each of resistance 5 Ω are connected in parallel. What is the effective resistance?
A particular resistance wire has a resistance of 3·0 ohm per metre. Find the resistance of 5 m length of a wire of the same material, but with twice the area of cross section.
