9.7 Ohm's Law--The Relationship Between Current, Voltage, and Resistance

Ohm's Law

Battery and bulb to explain, with numerical examples. Duration: 6:07

Electrical Resistance

How much electric current flows depends on both voltage and electrical resistance. The greater the electrical resistance, the less the current. Duration: 2:15.

Ohm's Law

The relationship between electric current, voltage, and resistance is spelled out as an exact equation known as Ohm's Law. Duration: 2:57.

Speed and Source of Electrons in a Circuit

The similarities and differences between electric and hydraulic circuits. Duration: 5:54.

Voltage Drop

Why the sum of the voltages across bulbs in series adds to battery voltage. Duration: 5:18
