A voltage of 5 V is applied across a colour coded carbon resistor. A current of 5 mA flows through it. What are the colours of second and third band of coded colour resistor?
Text Solution
AI Generated Solution
To determine the colours of the second and third bands of the colour-coded carbon resistor, we can follow these steps:
### Step 1: Understand the relationship between voltage, current, and resistance
Using Ohm's Law, we can find the resistance (R) of the resistor. Ohm's Law states:
\[ V = I \times R \]
Where:
- \( V \) is the voltage (5 V)
- \( I \) is the current (5 mA = 0.005 A)
