Question

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?

​

Answer 1

V = 24 [V]

Step-by-step 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]
