Ohm's Law & Circuits

OHMS

Ohm's Law relates voltage, current, and resistance in an electrical circuit. Battery voltage acts as the pressure driving charge carrier flow, resistance opposes this flow, and current represents the rate of charge transfer. Increasing voltage or decreasing resistance accelerates the flow rate.

I=VR,P=VII = \frac{V}{R}, \quad P = V I

Whiteboard Solver Steps

Step 1

Ohm's Law (V = IR)

The current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance.

I=VR=10 V20 Ω=0.50 AI = \frac{V}{R} = \frac{10 \text{ V}}{20 \ \Omega} = 0.50 \text{ A}
Step 2

Joule's Power Dissipation Law

Electrical energy is converted into heat energy in the resistor at a rate equal to the product of voltage and current.

P=V⋅I=10⋅0.50=5.0 WP = V \cdot I = 10 \cdot 0.50 = 5.0 \text{ W}
