Postlab: The circuit shown at right is composed of an ideal battery and five identical light bulbs. 1. Is the potential difference across bulb C greater than, less than, or equal to the potential difference across bulb D? Explain. B 2. Is the potential difference across bulb A greater than, less than, or equal to the potential difference across bulb B? Explain. Now bulb C is unscrewed from its socket, creating an open circuit. 3. Does the current through the battery increase, decrease, or remain the same? Explain. (Hint: What happened to the total resistance of the circuit when bulb C was unscrewed?) 4. Does the voltage across bulb E increase, decrease or remain the same? Explain. 5. Does bulb A become brighter, become less bright, or remain the same? Explain. (Hint: Use Kirchoff's Loop Law to support your answer.)
