A current of 2 mA is passed through a colour coded carbon resistor with first, second and third rings of yellow, green and orange colours. What is the voltage drop across the resistor?
Text Solution
Verified by Experts
For colour coded carbon resistor, the numbers attached for yellow, green and orange are 4, 5 and 3 respectively. Therefore, the resistance of the given carbon resistor, `R=45 xx 10^(3) Omega` Voltage `V=RI =(45 xx10^(3)) xx (2xx10^(-3))=90V`
