Question

Calculate the current and resistance a 10W,20V electric bulb in an electric circuit​

Answer 1

See the answer Below Mate :-

=>Firstly, we will calculate the resistance of the electric bulb.

=>We Know that,

                                           $R=V/I$

=>R = (20/10)Ω

=>R = 2Ω

Hence, we know the R(Resistance). Now, we can calculate the I(Current).

=>To, Calculate the Current of the electric Bulb.

=>We should know that :-

                                           $I=V/R$

=>I = (20/2)A

=>I = 10A.

Hence, the answers are :-

1)R = 2Ω

2)I = 10A.
