Aseries circuit contains two devices one with a resistance of 10 ohms and one with a resistance of 4 ohms if the generator supplies a voteage of 42 v what is the magnitude of the current?

i = 3 A

Explanation:

When two or more resistances are connected in series then the total effective resistance is given as

now we have

now from ohm's law we know that

here we know that

V = 42 volts

R = 14 ohm

now from above equation

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
