Question

Find the applied voltage of a telephone circuit that draws 0.017amperes through a resistance of 15,000 ohms.

Answer 1

Answer:

255 volts

Explanation:

according to ohm's law,

voltage = resistance x current

here

current = 0.017 amperes

resistance = 15000 ohms

so, voltage = 15000 X 0.017

= 255 volts
