Certified Control System Technicians (CCSTs) calibrate, document, troubleshoot, and repair/replace instrumentation for systems that measure and control level, temperature, pressure, flow, and other process variables.
What is the value of a resistor that is color coded: green - brown - orange - gold?
A. 51 K ohms ± 5%
B. 80 K ohms ± 5%
C. 51 ohms ± 10%
D. 503 ohms ± 10%
So a resistor with four bands,
green-brown-orange-gold, has a value of: 5 1 x 1000 ± 5%
Or 51 KΩ.
