" If a 701-Ω heating filament is carrying a current of 0.0700 A, what voltage drop will exist between the two ends of the filament? "
To find the voltage drop across the heating filament, we use Ohm's Law:
Resistance,
Current,
Ohm's Law states:
Voltage drop:

The two wires of a high-voltage transmission line are carrying 900 A to and from a city. The voltage between those two wires is 200000 V. In bringing electricity to individual homes, the power is transferred to low-voltage circuits so that the current passing through homes experiences a voltage drop of only 120 V. How much total current is passing through the homes of the city?
