CLICK HERE TO SEE QUESTION 4 4.1) In the circuit represented belоw, the bаttery hаs аn emf оf 15 V and an unknоwn internal resistance. Voltmeter V1 is connected across the battery and voltmeter V2 is connected across an open switch S. The resistance of the ammeter is negligible. The switch S is open. 4.1.1) Define potential difference. (2) 4.1.2) Determine the reading on voltmeter V1. (2) 4.1.3) Determine the reading on voltmeter V2. (2) The switch S is now closed. The reading on voltmeter V1 drops to 10,5 V. 4.1.4) Use a suitable equation to explain why the reading on V1 drops. (3) 4.1.5) Calculate the effective resistance of the resistors in parallel. (3) 4.1.6) Calculate the reading on the ammeter. (3) 4.1.7) Calculate the internal resistance of the battery. (3) 4.2) An electrician needs to replace a bulb that has a 220 V supply. Unfortunately, the only working light bulb in stock is rated 50 V, 100 W. 4.2.1) Calculate the resistance of the 50 V, 100 W light bulb. (3) 4.2.2) Calculate the current that should flow through the working light bulb. (3) The electrician uses the 50 V, 100 W light bulb and connects a resistor in series with the light bulb to ensure that the bulb operates at its correct rating when connected to the 220 V supply. 4.2.3) What should the resistance of the resistor be that the electrician connected in series with the light bulb? (3) 4.3) The circuit shows a heater connected to a 6V battery, an ammeter, and a component marked X. The heater is designed to work from a 3,6V supply. It has a power rating of 4,5W at this voltage. 4.3.1) Write down the name of component X. (2) 4.3.2) By considering the current in the heater, calculate the resistance of component X when there is the designed potential difference across the heater. (5) 4.3.3) Calculate the resistance of the heater. (3) 4.3.4) Some time after the heater is switched on, the ammeter reading becomes zero. Suggest why this happens. (2) [40]
