# Filament of bulb

The filament of bulb has a 1 ohm resistivity and is connected to a voltage 220 V. How much electric charge will pass through the fiber when the electric current passes for 10 seconds?

Correct result:

Q =  2200 C

#### Solution:

$U=220 \ \text{V} \ \\ R=1 \ \text{Ohm} \ \\ I=U/R=220/1=220 \ \text{A} \ \\ t=10 \ \text{s} \ \\ I=Q/t \ \\ Q=I \cdot \ t=220 \cdot \ 10=2200 \ \text{C}$

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
