Ohm I Goodness

Ohm I Goodness

Feb 14th 2024

In honor of Valentine’s Day, we'll delve into the distinctions between amps, volts, and ohms, shedding light on their roles and, ahem, relationships. Amps, short for amperes, measure the rate of electric current flow within a circuit. Think of it as the flow of water through a pipe: amps quantify how many electrons are moving through a wire per second. Volts quantify the electrical potential difference or voltage between two points in a circuit. It's akin to the pressure in a water pipe, pushing electrons along the circuit. Ohms measure electrical resistance within a circuit, determining how much the circuit impedes the flow of current. In simpler terms, it's like the narrowness of a water pipe—higher resistance means less current flow for a given voltage.

Voltage (V) = Current (I) × Resistance (R)

Ohm's Law highlights the connection between voltage, current, and resistance: increasing voltage increases current (assuming resistance stays constant), while increasing resistance reduces current (assuming voltage stays constant). The average bolt of lightning contains 30,000 amps and 300 million volts!
