Question

При подключение лампочки к круглой батарейке через нить накала протекает 6Кл за минуту. А при подключение к плоской батарейке 8Кл за 20 секунд. Во сколько раз увеличивается сила тока при смене батарейки ?

Answer 1

Формула силы тока I=q/t подставляешь I1=6/60=0,1A
I2=8/20=0,4A теперь I2/I1=0,4/0,1=4 ответ в 4 раза увеличилась сила тока

Answer 2

Calculation of Current Increase

To calculate the increase in current when changing the battery, we need to compare the charge flow in each scenario.

- When the light bulb is connected to a round battery, 6 kilocoulombs (6Kl) of charge flow in 1 minute. - When the light bulb is connected to a flat battery, 8 kilocoulombs (8Kl) of charge flow in 20 seconds.

To find the increase in current, we can use the formula:

Current (I) = Charge (Q) / Time (t)

Let's calculate the current in each scenario:

1. Round Battery: - Charge (Q) = 6Kl = 6000 Coulombs (C) - Time (t) = 1 minute = 60 seconds

Current (I) = 6000 C / 60 s = 100 Amperes (A)

2. Flat Battery: - Charge (Q) = 8Kl = 8000 Coulombs (C) - Time (t) = 20 seconds

Current (I) = 8000 C / 20 s = 400 Amperes (A)

To find the increase in current, we can calculate the ratio of the currents:

Increase in Current = Current with Flat Battery / Current with Round Battery

Increase in Current = 400 A / 100 A = 4 times

Therefore, the current increases by a factor of 4 when changing the battery from a round battery to a flat battery.

Please note that the calculations are based on the given information and assumptions.
