Answer
To draw the circuit diagram, include the following elements:
Battery Symbol: Represent the 9V battery using the standard battery symbol.
Lamp Symbol: Use the appropriate symbol for the lamp.
Resistor Symbol: Incorporate the resistor in the circuit using its accepted symbol.
Switch Symbol: Add the switch symbol, showing it in either open or closed form.
Connecting Wires: Ensure that all components are connected with wires, forming a complete circuit.
Make sure to follow the correct series circuit layout.

Answer
Using the equation:
extcharge=extcurrentimesexttime
Substituting the values:
extcharge=0.46extAimes30exts=13.8extC
Thus, the total charge that flows through the lamp in 30 seconds is 13.8 C.
Step 3
Calculate the energy transferred to the lamp in one minute.
