Question

How many 440 Ω resistors should be connected in parallel to draw a total current of 10 A on a 220V line

Answer 1

Answer:

You need 5A current over 220V voltage difference. So the total resistance of the circuit in between would be R=V/I, here R=220V/5A=44 Ohm . Now, you have only 440Ohm resistors which are to be connected in parallel only.

Explanation:

Answer 2

Answer:20

Explanation:

V/I = 22

440/22 = 20
