Maryam sets up a current,  , across a bulb in an experiment.What is the magnitude of net charge,  , flowing through the bulb in time,  ?

1. Break Down the Problem

To find the magnitude of the net charge $Q$ flowing through the bulb, we need to consider the relationship between current $I$, time $t$, and net charge $Q$. The formula that relates these quantities is: $Q = I \times t$ Where:

• $Q$ is the net charge in coulombs (C),
• $I$ is the current in amperes (A),
• $t$ is the time in seconds (s).

2. Relevant Concepts

In our case, we are using the standard formula for electric current, which tells us how much charge flows through a given point in a circuit over time. We will use this formula directly to compute the net charge.

3. Analysis and Detail

Substituting the values of $I$ and $t$ into the formula:

• If the current $I$ is known (for example, say $I = 2 \, \text{A}$) and the time $t$ is known (for example, say $t = 5 \, \text{s}$), the calculation would be: $Q = I \times t = 2 \, \text{A} \times 5 \, \text{s} = 10 \, \text{C}$ Ensure to replace these values with those provided in your experiment when performing the calculation.

4. Verify and Summarize

Make sure that the units are consistent when you substitute values into the equation. The charge calculated should reflect the cumulative charge that has passed through the bulb over the specified time due to the current flowing.

Final Answer

The net charge $Q$ flowing through the bulb is calculated using the formula $Q = I \times t$. Therefore, substitute the specific values for current and time to find the net charge in coulombs.
