A resistance of 60ohms allows 0.4 amps of current to flow when it is connected across a battery. what is the voltage of the battery?

V = 24 [V]

Explanation:

To solve this problem we must use ohm's law, which tells us that the voltage is equal to the product of resistance by the current.

V = I*R

where:

V = voltage [V]

I = current [amp]

R = resistance [ohm]

Therefore:

V = 0.4*60

V = 24 [V]

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
