✔ 最佳答案
resistance = R= 1 / ( 1/100 + 1/100 + 1/100 + 1/100 + 1/100 + 1/100 )R= 1 / ( 1/100 * 6)
R= 1 / ( 6 / 100 )
R = 100 / 6 ohm
I = V / R
I = 12 / (100 / 6)
I = 0.72 A
the total current when six 100 ohm's torch pulbs are connected in parallel across a 12v supply is 0.72A
I hope this can help your understanding. :)
