(c) Calculate the charge that flows through the cell in 1 minute. Each filament lamp has a power of 3 W and a resistance of 12Omega Write any equations that you use. Give the unit.

Answer 1

## Step 1: ### \( P = I^2R \) ## Step 2: ### \( I = \sqrt{\frac{P}{R}} \) ## Step 3: ### \( I = \sqrt{\frac{3W}{12\Omega}} = 0.5A \) ## Step 4: ### \( Q = It \) ## Step 5: ### \( Q = 0.5A * 60s = 30C \) So, the charge that flows through the cell in 1 minute is 30 Coulombs (C).

Answer 2

## Step 1: First, we need to calculate the current flowing through the filament lamp. We can use the formula \( P = I^2R \), where \( P \) is power, \( I \) is current, and \( R \) is resistance. ## Step 2: Rearrange the formula to solve for \( I \). The rearranged formula is \( I = \sqrt{\frac{P}{R}} \). ## Step 3: Substitute the given values into the formula. Here, \( P = 3W \) and \( R = 12\Omega \). ## Step 4: After calculating the current, we can calculate the charge that flows through the cell in 1 minute. We use the formula \( Q = It \), where \( Q \) is the total charge, \( I \) is current, and \( t \) is the time. Here, time \( t = 1 \) minute = 60 seconds (1 minute is 60 seconds). ## Step 5: Substitute the calculated current and given time into the formula to find \( Q \).
