Current strength, a value that shows what electric charge passes through the cross section of the spiral in 1 s.
I = q / t, where q – electric charge, t – time.
Substitute the numerical values and find the current strength:
I = q / t = 2/10 = 0.2 A.
Answer: the current strength in the bulb is 0.2 A.
