how many 176 ohm resistors are connected in series to get a current of 5 a on 220 v battey

Sagot :

Total resistance = voltage / current = 220 / 5 = 44 ohms .

Even one 176-ohm resistor is too much.  The current through it is 1.25 A,
and more than one of them in series reduces the current even further.

Connecting them in parallel, however . . .

Four resistors of 176-ohms each, in parallel, have a net effective resistance
of 176/4 = 44 ohms ... exactly what you need to do the job.
