5.5: Ohm''s Law

The current through the resistor and the voltage across the resistor are measured. A plot is made of the voltage versus the current, and the result is approximately linear. The slope of the line is the resistance, or the voltage divided by the current. This result is known as Ohm''s law: [V = IR label{Ohms}]

Ohm''s law | Voltage, current, resistance relationship

Ohm''s law is one of the basic principles of electricity. It relates the basic parameters of electricity, Current and voltage, to each other and with resistance. Georg Ohm, after whom the law was named, conduct a few experiments on circuits containing different lengths of wires and found that the voltage applied and current are directly proportional.

DC Parallel Circuits

Well lets look at resistor one first, current equals voltage divided by resistance. So 6V divided by 10 ohms gives us 0.6A. ... Say we have a 10 ohm and a 5 ohm resistor connected in parallel to a 6V battery. R1 has a current of 0.6A (That''s 6V / 10 Ohm = 0.6A) So the power consumption of the component is 3.6Watts. We see that from 6V^2 …
