Testing Ballast Resistors

Specifications

Ballast resistor 1 No: BR1

Ballast resistor No 1 ohm spec: 2 ohms

Measured Resistance Values

Ballast Resistor No 1 Measured Ohms: 2 ohms

Serviceable? Yes



Measuring Current Draw and Voltage Drop

Current Draw : 3.39A

Coil calculated Voltage Drop : 1.3 x 3.39 = 4.407

Coil measured Voltage drop : 4.77V

Ballast resistor calculated voltage drop : 2 ohms x 3.39 = 6.78V

Ballast resistor measured voltage drop: 4.9V






Did your calculated values equal your measured results explain why or why not?

Yes it does equalswith measured results, although the second time I checked the resistance of the ballast the resistor I got was much less resistance ( 1.67 ohms ) because the first time I checked it the resistor was much hotter which increased the resistance.
