So, the charge that flows through the cell in 1 minute is 30 Coulombs (C).
Explanation
## Step 1: First, we need to calculate the current flowing through the filament lamp. We can use the formula
, where
is power,
is current, and
is resistance. ## Step 2: Rearrange the formula to solve for
. The rearranged formula is
.## Step 3: Substitute the given values into the formula. Here,
and
.## Step 4: After calculating the current, we can calculate the charge that flows through the cell in 1 minute. We use the formula
, where
is the total charge,
is current, and
is the time. Here, time
minute = 60 seconds (1 minute is 60 seconds).## Step 5: Substitute the calculated current and given time into the formula to find
.
