Question

Calculate power of lamp​

Answer 1

Answer:

Total resistance in the circuit=24ohm

Total current across the circuit=0.25I

Potential difference across electric lamp=5V

Potential difference across conductor=1V

Explanation:

A)As conductor and bulb are connected in series

Total resistance R=R1+R2

Which is 20+4=24ohm

B)I=V/R

So I=6V/25 ohm=0.25A

C)0.25*resistance of lamp=0.25*20=5V

D)0.25*resistance of conductor=0.25*4=1V
