Expert Solution & Answer
Check Mark

Answer to Problem 51A

Resistance to be used =  160 Ω_

Explanation of Solution

Given:

The following figure:

Battery’s voltage = 6.0 V

Potential difference across LED = 1.2 V

Current through the LED = 3.0×101 mA

Formula used:

The power supply voltage is given by,

  Vb=IR+Vd

Where I is the current, R is the resistance and Vd is the potential difference.

Calculation:

Resistance is calculated as:

  R=VbVdI   =6.0 V1.2 V0.03 A   =160 Ω

Conclusion:

Resistance to be used =  160 Ω_
