Checking Amps
In this video, we discuss how to check amps, and we learn how to either apply Ohm’s or Watt’s Law to find current draw.
Summary
- Per Kirchhoff’s Law, current is the same throughout a circuit. You only clamp around one wire in the circuit to check amps.
- Ohm’s Law applies to getting current for resistive loads (such as a bake element).
- Watt’s Law applies to getting current for inductive loads (such as a motor).
- A load may test good for Ω, but could have mechanical resistance causing the issues.
