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

Physics

Phantasy [73]3 years ago
4 0
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 <em><u>parallel</u></em>, however . . .

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

Which object experiences the greatest gravitational force? A)car B)fire truck C)plane D)human
Svetlanka [38]

Answer: C Plane

Explanation: According to Newton's law, gravitational force is proportional to the product of masses and inversely proportional to the square of distance between them.

Gravitational force depends on mass. The bigger the mass, the more the magnitude of the gravitational force. Since plane is assume to have the highest mass in the options, we can therefore conclude that plane will experience the highest gravitational force.
