The bulb

The bulb has a reading of 6V-0.05 A, what current flows through the bulb if we connect it to a cell with a voltage of 12V?

Correct result:

I2 =  0.1 A

Solution:

U1=6 V I1=0.05 A U2=12 V  R=U1/I1=6/0.05=120 Ω  I2=U2/R=12/120=110=110 A=0.1 A



We would be very happy if you find an error in the example, spelling mistakes, or inaccuracies, and please send it to us. We thank you!
