Here's the small resistor
Why: I need to measure current drawn by a large motor (from electric lawnmower), but my multimeter has a max rating of 10Amps. Workaround is to attach a known resistor in series and measure the voltage drop across the resistor, then use ohms law to solve for current in the circuit.
This resistor has a power rating of 250mW. Based on other lawnmower motors, I am assuming this is approx a 350W motor, and with a 24V source, the current will be around 15Amps (using P=IV).
Question: If I place such a resistor into the circuit, will the resistor blow up, or will it SAFELY dissipate whatever small amount of energy it is capable of absorbing and let the motor take the rest?
