How this service works
Solve volts, amps, ohms and watts from any two known values, with milliamps, kilohms and a recommended resistor wattage rating with a 2x margin
Output
Returns a JSON object with volts, amps, milliamps, ohms, kilohms, watts, milliwatts, a minimum resistor wattage rating (raw value), a recommended common power rating string (e.g. '0.5W') representing a 2x safety margin, and optional note and source fields for context.
Example use cases
LED resistor wattage check
“I'm building an LED circuit running at 5 volts with a 220 ohm current-limiting resistor. What's the power dissipation and what wattage resistor should I safely use?”
Automotive circuit current draw
“My car accessory runs on 12 volts and is connected through a 2.2 kilohm resistor. What's the current draw in milliamps and how much power is being used?”
Bench power supply load calculation
“I'm running a 9 volt bench supply through a 1000 ohm load resistor — what are the amps, watts, and minimum resistor wattage rating I need?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/electronics/ohms-law?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, reliable Ohm's Law computation that goes beyond a basic formula — specifically when you want milliamp and kilohm conversions alongside a practical, safety-margined resistor wattage recommendation in a single call. Ideal for electronics hobbyists, makers, or agents building circuit-assistance tools where recommending a safe component rating matters.
Side effects
- Missing required query parameters (v for volts, r for ohms) results in an error response
- Non-numeric or invalid string values for v or r may cause computation errors
- Zero-valued resistance could trigger divide-by-zero handling
- Payment failure (402) if x402 USDC payment is not completed before request
