Help me with a question please /sci/.

If 93.6*10^12 electrons pass through a lamp in 5 ms, what is the current?

>> No.1768423

current is charge/second

(93.6*10^12 electrons)*(Charge/electron) / .005 seconds

I dunno what the charge / electron is, look it up

>> No.1768431

7 grams

stop doing peoples homework

>> No.1768435

6.242×10^18 electrons per second is one ampere

>> No.1768457

>>1768435
I know that... I don't know how that helps.

>> No.1768458

>>1768433

k, ill go make myself a troll thread instead

>> No.1768467

number of electrons/time = electrons per second
electrons per second/6.242×10^18 = ampere

... you're right. Thank you
